Need help identifying age

[T Hunter]

These 2 nuts and bolts were found in an area of a known 1774 shipwreck . They don't look that old to me but i wanted to ask the experts. They were both encrusted an i put the 1 in electrolysis and left the 2ND one for now the way i found it .Any help would be greatly appreciated. Thanks Mark Please see pictures.

Those nuts are modern. Nuts from 1774 would probably have been square. Tony

If there is a slot on the top part, it may be part of a rocker arm/valve assembly.

Everyone else is just guessing...I actually did a spectroanalysis and determined that it was manufactured in 1902...March 1st, to be exact.

I'm not sure that anyone can be exact as to when your nuts came into being...

In the trash they go .. Thanks again Mark

Electrolysis worked well.
Nut and bolt.

Can you get the nut unscrewed from the pin? I would like to see the machined threads. It looks like a turned, screw machined, cold headed part from the early 1900's.

I have a friend who is a blacksmith. He works in traditional ways with traditional tools and I have brought him several pieces of hinges, hooks, nuts, bolts, hasps, etc. He always does a spark test to identify the metal. It's relatively simple... just take the object and touch it to a grinding stone in an indiscreet spot on the object. You can then tell what the metal is, and if it was forged/cast by the sparks trailing the grinder. He has a very small, fine grinder for doing this, and is quite accurate in his observations. Simple and easy to do. I'm sure there is more info on this subject on the internet. The downside of this is that to test the metal you need to grind a spot, so I wouldn't recommend it for a very rare or valuable relic. HH Michelle
