Age of 3-inch long nail with round upper shank?

I am hoping to identify this nail. It is 3 inches long with a head dia of 9/16". The upper part of the shank is round, and the lower part is forged to a rectangle with a chisel point. There is a 'W' forged into the countersunk head.

What is its purpose, and how old is it please? - 2021-10-29 by Steve Campbell-Wright

@Steve Campbell-Wright,

The round upper shank of your nail makes it a modern fastener.

Could cut nails have appeared in Duncan Creek at gold rush sluice boxes?

My grandfather and his siblings and parents were part of the Klondike gold rush, 1898-1904. He wrote in a newspaper, decades later, about his father's mining group, “While on the prospecting trip the party went into the Duncan Creek area which later became the fabulously wealthy Keno Hill and Mayo country.

Here they found sluice boxes nailed with nails that had been cut rather than moulded.

This indicated prospectors had been in that area in the early ‘70’s and ‘80’s – long before the Klondike strike in 1896."

Do you have any idea if this statement has merit? And do you know what types of nails would have been used during the 1896-1899 timeframe in Yukon Territory, vs. earlier than that?

Reply by (mod) - early machine-cut nails made by 1790

@Jason M Gould,

Above courtesy of Phillips (1993) is an illustration of the 1814 Reed Cut Nail Machine patent, found in the patent infringement lawsuit papers in Oiome v. Amesbury Nail Factory (1819) at the regional office of the National Archives, Waltham MA.

It certainly has merit. Nails were cut from forged blanks, even by hand-operated machines at least from the early 1800s and possibly as early as 1790. (How, 2018 & How, 2009 ) (Phillips, 1993).

Cut nails were valuable, and in addition to being made by small hand operated machines would have been imported from England, from France, and perhaps also made further West in the U.S. or shipped to that coast.

That is to say it's more-likely that nails used to build gold mining apparatus, sluices, etc. would have been imported from more-remote larger cities where nail fabricators were already established.

Phillips notes that

By 1788, Adam Rogers, of Marshfield, had developed a machine that "cut nails from hoops or plates," and by 1792 his nephew, Samuel Rogers, was cutting nails "by hand in a small machine invented by him.

When cut from nail plate, the nails produced by the hand-operated machines would probably have had characteristics similar to those of nails manufactured a few years later, but with less refinement.

The earliest cut nails would have had shanks with two tapering and two parallel sides and burrs on diagonally opposite edges (having been cut from the same side of the nail plate), like their later cousins.

However, because of the crude, somewhat uncalibrated method of cutting, the shanks in cross-section would probably have appeared as skewed rectangles or parallelograms, rather than true rectangles (Fig. 2).

The nails would have had rounded ends (from the edge of the nail plate) and were probably initially hand-headed, sometimes with faceted rose or "T" heads found on wrought nails, other times the upper end simply bent over to produce a brad.

Eventually, crude heading machines may have been used.

Age of shipwreck nails found in the Philippines

@inspectapedia.com.moderator,

Can you identify what metal been used on these nails. My brother found these on unknown wooden shipwreck buried in the sand along the shore in the Philippines. - On 2021-10-15 by Christian Manalo

Reply by inspectapedia.com.moderator (mod) -

@Christian Manalo,

To get a general idea of the composition of those tacks or small nails

1. use a magnet - to see if they're iron or steel vs. perhaps brass or another non-magnetic metal

2. scrape the surface to see if you observe shiny brass or copper

From just the photo they look like galvanized iron

Thank you for the photo.

Very nice; looks like brass or copper; am I right?

A bulbous headed tack / nail of matchstick size might have been used where its head was left exposed to view, such as a decorative nail in a door or other building feature; smaller gauge tacks with decorative heads also show up on upholstered furniture.

Any information about the history of the specific site in the Hague might give us more clues.

On 2021-07-03 by inspectapedia.com.moderator (mod)

@Keith,

That is certainly a remarkable Spike. I don't know what it was for. Possibly Timber framing.

Sometimes people cut grooves in the spikes to improve their resistance to withdrawal but more-likely their regularity suggests that those are grip marks left by machinery used in nail or spike production.

I would like to make bronze cut nails. What thickness bronze plate should I cut them from?

On 2020-11-15 - by (mod) -

Mark

We need to start with a decision on what sized nails you need. The plate thickness determines the dimensions of the nail shank.

If you're not sure, just pick up a nail whose design you like. There is no one "right size" nail stock plate.

Consider that the nail length and width and taper vary, and the nail type and size range is huge, from tiny brads to structural fasteners.

Just as example data points,

a No. 8 common nail has a diameter of about 4.115 mm wire.

Hi there! We bought an old house and we can't seem to find out when it was built. We found square nails in the attic and wondered if it would help us figure out about when the home was built. What do you think?

On 2020-10-09 - by (mod) -

Amy

Take a look at NAIL AGE DETERMINATION KEY at https://inspectapedia.com/interiors/Determine-age-of-old-nails.php

and look for some of those features on your nail, for example: in your photo I note that the nail taper is not uniform, but has a widening area under the head; up close you may be able to see burrs on one or more of the four edges, and you may be able to see that the head was machine stamped (making it modern);

Of course a nail alone isn't the age of a home, as nails come into a building at various times and uses, so where it's found and fastening what to what are important.

Also we have an entire series of articles on how to determine the age of a house, starting at AGE of a BUILDING, HOW to DETERMINE https://inspectapedia.com/Design/Age_of_Building.php

Please take a look and don't hesitate to ask follow-up questions.

On 2020-10-09 by Amy

Thank you for the resources! I guess I just thought this would help to figure out what time frames we were looking at for construction here. From what I can tell, the nail head and from the nail head to the shank is irregular, but the shank towards the very bottom is more uniform. Here's another picture of it and another one that we found up there as well.

On 2020-10-09 - by (mod) -

Yes that larger-headed nail looks hand-wrought. The two nails look of different age to me.

Remember to note just where and how the nail was used; for example if we see what appear to be original nails in original framing of a building we can figure they're probably as old as the structure while if we're seeing add-on structure or materials obviously we can't assume that.

Take a look at the other building age clues in this article series - when deciding the age of a building it is important to use all of the available evidence and to correlate it; saw kerfs or marks, hammer marks, timber surfaces, other building hardware, architectural style : there is plenty to consider.

Rebuilding an 1850s home in Wappingers Falls NY I was thrilled to find, on tearing up a damaged floor below a toilet, old newspapers that pretty much told me the date at which plumbing - at least the toilet - had been added to the home.

The plumber stuffed newspapers all around the toilet bend - maybe hoping that if his work leaked it would not be discovered until after he'd safely escaped.

On 2020-10-10 by Amy

I'll have to investigate further! Most of the house has been renovated extensively so the attic and anything we can figure out inside of it is our only hope! Thank you!

On 2020-10-10 - by (mod) -

Amy:

Often there are many additional house age one can find, even in a renovated home, by careful inspection; layout, architecture, site debris, and the several topics suggested in

the ARTICLE INDEX such as saw marks on original framing lumber that you may see in the attic, basement or crawl space.

Is this an older nail or modern?

On 2020-10-08 - by (mod) -

Brenda I don't see the nail at all. But if you are referring to a wooden peg used to join wood furniture parts, those have been used for hundreds if not more than a thousand years and are still used in the present by some craftsmen. A few years ago I built a reproduction of a Shaker end table that was assembled using glue and wooden pegs, with no metal fasteners.

On 2020-07-06 by Sarah

I am trying to find out how old this nail may be and if it is machine or hand made.

It is about 80mm long and the head is about 11mm wide and although round, not a perfect circle. It does go to a point rather than a blunt tip. It's very rectangular all the way down. It does feel a bit more round directly under the head, but also looks like 4 distinct sides, so I'm not sure if the roundness is due to actually being round or due to corrosion.

I've clean it the best I could in the photos. I found this yesterday while digging a garden in my yard. Location is Suffolk England more specifically Mildenhall. Even more specifically... near an old mill that was recorded as being around since 1066.

Most info on the mill I could easily find including pictures was during the 1800s(Parker's mill)

Any help with an approximate date and if it's hand made or machine made would be awesome! Every thing I have been reading has just confused me more.

On 2020-07-06 - by (mod) - Round-ish 4-sided hand-wrought nail age, Suffolk England

Sarah:

Re: age of hand-wrought round headed nail in the UK

[Click to enlarge any image]

That looks like a hand-wrought nail to me, though it won't be as old as 1066, more likely the early 1800's. I'm basing that guess on

- the round-ish but not uniformly-round tapered shank - if the shank is actually flat-sided then it's an early cut nail, probably with a hand-wrought head

- the off-center point or tip

- the rather thin and irregular rounded head on the nail

- what appear to be remains of hammer marks along the shank

Thanks for the photos and question, Sarah.

"Machine-made" bears some discussion and clarification; even in the 1700s people were using hand or foot-operated levers or "machines" to cut nails from heated iron blanks, then hand-forging the nail head by inserting the nail into an opening in an anvil or similar device.

That's an operation that was distinct from fully-mechanized steam, water, or later electric-powered nail cutting machines and of course all of those continued in production overlapping "modern" round wire-based nails that are more-easily distinguished.

In this article series we discuss iron fibre direction (across vs along the nail shank), and head design, and tapering of nail shank, and cut marks on nail edges as further age-clues.

That rose head may indicate that the nail is old enough that the head was hand-forged after the blank was cut.

I have extracted these machine cut nails [photo above] from an historic English style barn dated on plaque to have been built in 1810.

I am trying to verify this date as I understand machine cut nails were a brand new idea in 1810. I have found no blacksmith nails in the structure although the timber framing is held together with tree nails - wooden pegs.

I would appreciate any help in aging these nails. Thanks much.

Thanks for the photo and question: cut nails in an 1810 English style barn

- located where? In the UK? U.S.?

The nails have a uniformly-tapered shank and what looks like a machine-made head that is uniform around the nail shank - making them look fairly-modern to me. Is it possible that they were added later?

- Where were the nails - holding what to what? - any photos of the nails in-situ?

I think these are "modern" cut nails - post 1830 and possibly newer.

Take a close look for splits along the nail length giving the direction of grain of the iron,
and take a look at any remnants of burrs along the nail shanks showing the direction of cutting.

Based on other findings in the immediate area, we believe we have discovered a shipwreck on a local Connecticut beach. [Photo above]

We were hoping to receive some help based on the nails we have uncovered - some still stuck in the deteriorated wood we dug up.

There were numerous wrecks along this beach during the 1800’s - being able to identify and date the nails might help us determine which one!

Thank you for any input or information.

On 2020-06-13 - by (mod) - possible Connecticut Shipwreck nail

Ryan

Well that's certainly a cut nail but it's tough to see details.

I note a tapering under the head but can't tell if that widening along the shank is how the nail was made (an older one) or if it's simply accumulated exfoliated iron.

Those details are in the article NAIL AGE DETERMINATION KEY

See if you can see any splits long the length of the shank - that gives a detail about the iron "fibre" direction that in turn can date the nail.

I found this in a piece of timber that floated ashore on the south west tip of Ireland. Because of the Gulf Stream it is possible it crossed the Atlantic

On 2019-05-30 by (mod) -

James,

Thank you for a very interesting nail photo. It's possible that it did cross the Atlantic of course not by swimming or floating but buoyed by wood.

What's interesting and unusual are those regularly spaced ribs which may have been made deliberately to avoid withdrawal that is to create withdrawal resistance. That might help us or other readers make a suggestion of what the nail was for. Straighten. It looks as if it would be more than 6 in long it's a pretty big spike. Probably securing or nailed into a Timber.

On 2019-05-30 by JamesMcKenna

Thanks mod, It was indeed in a large beam of timber that was floating off the shore.

I pulled it out by hand so loose it was. It's 7.5 inches in length with those ripples running the entire length. I pulled the timber ashore and stashed it above the high water mark so I can go back and take a picture of it although it is in a remote part of the shoreline that is hard to access. Will come back with more later. Thanks for your reply

On 2019-05-31 by (mod) -

It will be interesting to see photos of the Timber itself. Often tool marks can give us some indication of the timber age.

On 2019-06-01 by JamesMcKenna

The plank is 8' x 6" x 3", roughly hewn. It could have lost it's edges over years under or on the water. The spike weights 126 grams. My feeling is that it was submerged in the ocean for a long time but broke free and floated up.

Generally timber that has been floating on the water for a long time has been eaten by ship worms and is full of holes. This doesn't have much ship worm activity. This could be that it's a type of wood they don't like.

On 2019-06-01 by (mod) -

Quite so, though I don't see obvious hand-hewn marks there are a few very faint ones. Also on some boats or ships the level of carpentry was more-skilled than and finished wood surfaces smoother than timbers used in barn and building construction.

On 2019-05-19 by (mod) -

Mark,

It's possible: some wooden ships used massive beams - as much as 16" square.

If your left-hand nail in the photo - the one against the plain side of the ruler - is round as it looks to me, that's a more-modern spike.

I came across this "nail within a nail" on our property, which was the site of a butcher shop and a dry goods store dating back to the 1880s. (We live in a historic California Gold Rush town.) Do you know what it's called, and what it was used for? Thanks in advance.

Thank you for the very interesting nail-in-nail example and photo - honestly it's not something I've seen before. It looks as if the smaller nail was being used to affix a hanger-spike to a timber or beam. Or possibly this was a hand-forged spike whose original fabrication attempted to build up the iron spike by combining older materials into one.

I'm doing some research and will post further findings here.

Those parallel grooves also referred to as a "fluted shaft nail" on the nail shank look like a modern hardened masonry nail.

These nails, typically hammer-driven into concrete, are also sold in a magnetized version used by surveyors, such as the ChrisNik Magnails shown below.

Thank you for the interesting photos and question. I can't make out much detail but your nail on the right of your ruler is a cut-nail, giving a rather broad date range as you'll see in the home page at the recommended articles (end of this page) for this topic.

This is a GREAT resource!

I found a slope lap desk at our Salvation Army and fell in love with it. Its felt writing surface was totally rotted, so I'm preparing to clean it off so that I can actually use the desk.

About a zillion nails were used to secure the felt at the hinges; getting them out was a chore because they were also glued in place, my guess is with resin. This made examining the nail holes extremely difficult.

Some of your pictures are very similar to these finishing nails, but I wanted to show them to you. If you have any input, I'll be grateful for it!

On 2020-10-11 - by (mod) -

Those are nice photos of modern machine made tacks, Sophia. Can you also post an image of the lap desk?

On 2020-10-11 by Sophia Kelly Shultz

The desk can't be closed right now because the glue is still drying. The outside is very plain; we think it is walnut. The inside is pine. There's a stamp on the back that reads something like "Wilburmilk" (no joy on Google). It's a rubber stamp. The glue fluoresces green, and when wiped down with a damp cloth smelled like resin.

On 2020-10-11 by (mod) - age of tacks & hardware in Wilburmilk lap desk

Those are particularly nice brass hinges - making me guess the hardware and perhaps the folding lap desk are from the 1850s but those tacks are curious. Tacks were one of the earliest machine-made metal fasteners, as you'll see in the history given in this article series. Blanchard's machine dates from around 1806.

See if you can identify other instances of the hinges or of the lock mechanism.

Knowing the context is often a basic starting point for guessing the age of building components, furniture, hardware, lap desks.

City
where found
age of buildings in the area
history of acquisition
etc.

On 2020-10-12 by Sophia Kelly Shultz

My husband and I agree that the tacks are after-market, possibly used if the felt was replaced at some point.

This would account for the glue which held the tacks in place. My feeling is that the person who owned the desk was unhappy with their repair, and nailed the felt down so that it wouldn't distort when the desk was closed.

We are in the US, Pottsville, PA. I found it at the Salvation Army in Pottsville. I work as a volunteer: we do receive a fair number of antiques and I spotted it before it made it out of the back room. Our house and the house next door are dated 1864. Pottsville itself was incorporated as a borough in 1828, and there are buildings from that era still extant.

The town's location on the Schuylkill River and in close proximity to the Reading and Pennsylvania Railroads makes it quite possible that the desk was brought from elsewhere, perhaps from Philadelphia.

On 2020-10-12 - by (mod) -

I agree; though there is a very long history of machine-cut carpet and other small tacks, your tacks are probably carpet tacks, or possibly upholstery tacks that look rather modern.

Found in the water in a lake in Ontario, Canada - very heavy. Can chip off the crust. Haven’t finished....

One side has some tool marks running perpendicular. Weight 3-5 pounds. The head is irregular and the whole thing is on a slant.

Is this a nail? Or a wedge or spike? Having a hard time finding out what it is...

Hello! I found this in the water (about a foot under the sand). We chipped away at it a bit and the crust around it came away. It smells a bit like rotten eggs. I’m having trouble figuring out if it’s a nail or a spike or a wedge.

It’s very heavy (about 3-5 pounds.) Any help would be appreciated.

On 2020-08-23 - by (mod) - hand forged wedge from Lake Ontario?

This may be a wedge, hand forged, used in log splitting.

Very interesting; can you give dimensions?

Thank you.

On 2020-08-23 by Allie

Thanks! It’s 6 inches and two inches wide. The thickest part of the wedge in the first picture is 1 inch.

Picture of one side. It looks like it’s staring to corrode after we removed some of the crust.

Found this in a piece of waterlogged wood down at Westmoreland State Park on the Potomac in VA. The piece of wood also had what looked to be a wooden peg in it, I tried but couldn't pull that out. I was able to remove this brass spike though.

From what I can tell online it seems to be from a sea-going ship from 150-200 years ago. Curious if anyone has any other information that might help date or shed light on where this might have come from. Thanks!

On 2020-08-06 by bela Lajos - antique nails from Budapest, castle district

Found these in the old castle district in Budapest, which has been the site of countless battles ranging from early Roman times to the late 1800s.

What kind of nails have this strange shape, if they are nails at all?

I have been finding these in the Budapest caste district while metal detecting.

The castle has existed since early Roman times and has been the site of countless battles from that time all the way to the late 1800s. What I am wondering is what kind of nails are these, if they are nails at all?

I have never seen such nails that look like arrowheads, but have been told to ask here.

Question: are these nails and bolts from a ship?

2019/10/12 David asked

Hello, Can you please tell me how old this hardware is and If it would of been used to make a ship or not? I found them in water so they are weathered. I’d really appreciate it!

Thank You!!
David

Reply: nails, bolts, rivets used in shipbuilding date back over 2,400 years

Hi David

You have an assortment of bent and straight iron hardware there; a cut nail or two, a nut and bolt assembly, and a large machine made bent spike.

The lines of the spike are least rusted and thus it's easiest to examine for hand-tooling marks (none found); I think this is mostly modern hardware, the spike perhaps from post and beam or dock construction.

NAIL AGE DETERMINATION KEY can help you make an informed guess about the the age of these fasteners.

Were these fasteners used to make a ship? Early wooden ships used large wooden spikes to secure mortise and tenon joints - "Treenails"; as water, especially salt water is corrosive, metal nails of later ships and boats were galvanized or bronze.

Unless we have more context I can't make a useful guess at that answer; a wide variety of fasteners, including spikes, smaller nails, rivets, and screws were all used in shipbuilding.
More modern nails used in wooden boats are copper or bronze, typically ring-shanked with wide heads. Cut nails produced as rosehead square shank spikes of lengths from 50 to 200 mm long are still produced.

Metal nails used in ships have an ancient history as cited in this example research

• Shalev, S., Y. Kahanov, and C. Doherty, NAILS FROM A 2,400 YEAR OLD SHIPWRECK: A STUDY OF COPPER IN A MARINE ARCHAEOLOGICAL ENVIRONMENT [PDF] JOM Journal of the Minerals, Metals and Materials Society 51, no. 2 (1999): 14-17.
  
  Abstract: The metal nails that fastened the wooden components of a 2,400 year old ship found along the coast of Kibbutz Ma'agan Mikhael, Israel, were made of unalloyed copper that was intensively hammered. A lead isotype analysis of one nail indicates with high probability that it was made of copper from Cyprus.
  
  The copper of the nails in the wood was replaced entirely by copper sulfide mineral, displaying the occurrence of deep anaerobic conditions in a breaker zone under a shallow cover of sand. the slow decay of the cellulose and hemicellulose in the wood is a possible explanation for the specific necessary environmental conditions.

Hi .... I have another pic of the old spike I found which has I think the #1 stamped on it

Reply: Antique wire fencing nails

I noted by email that may be a wire fencing nail.

In the U.S. there was an explosion of nail inventions in the last half of the 1800s including a range of nails used in fencing, some with special heads to hold wire against the wood post and some including a protrusion that made removal of the nail with a hammer easier should fencing repair or adjustment be needed.

And let me know what those tell us

On 2019-05-01 by CR

I gave it a quick clean up, removed most of the rust.

So here is another photo. I’ve never seen something like this before and haven’t been able to find any similar examples online. I’m not even 100% sure it is a nail but that’s my best guess.

On 2019-05-01 by (mod) -

Nice job and photo; your cleanup of the metal spike? shows a very square head and straight line sides suggesting this is a machine made nail or spike; next time include a ruler in the photo so we have an idea of its dimensions.

On 2019-05-01 by CR

Ahh yeah dimensions would be useful. Another photo included. After some more clean up I’ve found some more details.

There is a clear seam on top of the head where the shaft was attached to the head like a collar. The metal also shows some interesting patterns not sure if this is from weathering or the type of metal/manufacturing. I would like to believe this is a nail but seems unlikely that this can really be classified as such.

 

 

 

 

Mod Reply: - Thanks CR this looks like the rusted-off head of a large spike - such as I'd expect to see in post and beam construction or at the seaside, dock construction.

Knowing what was around where you found the nail, old buildings, seaside, history occupancy, etc. would also be helpful.

I suspect from the rust patterns that the "grains" in the iron run parallel to the shaft direction, making this one of the more-modern alloys - perhaps after 1830. (I need more research on nail fabrication in Wales and the rest of the UK).

Nail fabrication in the UK dates from Roman times but machine made nails are of course modern.

In general in the UK cut nails or machine fabricated nails are not likely to be dated earlier than 1811 - the earliest report I have found was of Joseph Dyer, established cut nail fabrication in Birmingham ca 1811.

I've added some UK citations in the history of nail fabrication references in the article NAIL AGE DETERINATION KEY (live link at end of this page) (you may need to refresh your browser cache to see them).

Pay particular attention to the PDF file about the Ewbank Nail listed under Australia nail history as this nail was also used throughout Britain.

Therein see the square-point nail from 1893.

I recently came into possession of an old picture frame. The frame has two old nails holding the hanging wire on. Can you please tell me when this nail was made and how it was made? The nail is 1/2 inches long. Thank you so much.

On 2019-04-19 by (mod) - machine made tack

Kathy

While this could be an early machine-made tack it's definitely modern - machine made, not hand forged. Notice the smooth flat head, absence of hammer marks, uniformly tapered edge, and that center ridge that may be from a cutting machine. Those details place the nail in the outline of dates on the page NAIL AGE DETERINATION KEY (live link at end of this page)

No earlier than 1848 - assuming your picture frame and nails were made in North America - and possibly as late as yesterday.

Bak in the early 1970s while exploring the coastal caves out near the entrance to the San Francisco Bay with friends when I was a kid, I spotted this spike wedged down in the rocks at low tide. Stupidly (kids are fearless-- no judgement)

I climbed down to get it. I've had it ever since and never really knew where it may have come from or when it was made.

It measures approx 13.5 inches with a 1 inch diameter shaft and a 2 inch diameter head. Any ideas?

On 2019-03-28 by (mod) - round nail shaft diameter and symmetrical cut-point

Stew

The you perfectly round shaft and regular cut points suggest me but it's not a very antique spike but it is an interesting one. It's quite clear from the weld marks on the shaft that it was welded to some other structure and of course as you've doubtless noticed, the head has been smashed as well.

 

On 2019-03-18 by Tracy

I found this nail in a load of gravel in Missouri. It looks to me like its a hand wrought nail, but I really have no idea. Any thoughts?

On 2019-03-28 by (mod) - irregular nail shaft diameter and rectangular edges vs round nail shaft

Tracy

The irregular nail shaft diameter and remains of somewhat rectangular edges make this look like an antique cut nail or possibly a hand wrought nail. But I'm not sure from your photo.

If the nail is essentially round in cross section it's a modern wire-drawn nail.

I can't see the head in the photo but it looks as if you're handling around, machine-made Spike of considerable size.

Thank you for your reply!

On 2018-12-27 by (mod) - ding or hammer marks on old round nails may mean salvage & re-use

RE: Cat's round nail age:

if there were hammer marks on a round nail: such ding marks on a round nail could be from straightening a bent spike for re-use.

These were valuable back when - depending on the location, even in the 1930s and 1940s in some areas of the U.S. younger family members were put to work salvaging nails and spikes from old wood and straightening them to pass them on to their carpenter dad or uncle. (cf. P Galow, PA)

Your nail looks more as if many indentations are pitting from corrosion.

hi. i'm trying to get a guesstimate on age of wire nails with inconsistent heads. slightly different sizes and some a bit offset to center.

i've searched and searched but can't find information about when wire nails became consistent with head sizes and when things were still rough... any help would be appreciated. thanks! (no image due to broken phone)

On 2018-05-10 by (mod) -

I don't think manufacturing inconsistency is going to give us a date for when the nails were made. I see that sort of inconsistency even now depending on the fabricator.

How to tell age by nails. Chestnut beams

On 2017-05-15 by (mod) -

Regarding Chestnut beams, you haven't asked a question but I'm guessing you're asking the relationship between the presence of chestnut beings in buildings and building age.

If we exclude recycled use of old beams in newer buildings, in the United States the chestnut blight had taken a major toll on chestnut trees by 1940.

So it's safe to figure that by the nineteen-fifties those beams would have been rare in most buildings.

Beyond that, in my opinion more significant to look at the types of saw kerf marks or tool marks on beams as part of guessing their age.

We have some comments about the relationship between type of nails and building age

in NAILS, AGE & HISTORY and also in the comments below for this article.

Please take a look and let me know what you think. Because nail making machine reappeared in different parts of various countries and different times there's no single correct answer to the significance of a machine cut nail without considering the geographic location.

Can you tell the age of this nail 5 1\2" long

Square the bottom half. Wor320@aol.com

Sorry not letting me paste pic

On 2017-05-10 by (mod) -

Dave, I took a look at your excellent photo and later if it's ok with you I will post it

at NAILS, AGE & HISTORY.

However I could not see for sure that the head of the nail was hand-forged. You might take a close look for Hammer marks. It's also the case that the age of a nail depends in part on where in the world or country it was first used.

That's because in the US for example machines that made cut nails appeared earlier on the East Coast then in the middle of the country or farther west. If the head and body of the nail are hand rough, most likely it was made before 1800 if your property is on the east coast of the US
