Tool Time: Are these RIVETS old or modern?

[Breezie]

Hey Gang, I went out today to the same area that has produced several nice Civil War pieces, and dug these 2 rivets. They do not attract a magnet and measure 7/8 of an inch. The tin sheet is very substantial even though it is thin. So are they modern or old? Thanks, Breezie

I'd guess they are copper rivets, dating them may be hard though. those kind are still sold today.

Ken, thank you for your reply. Maybe my question should be: Are copper rivets the same today as they were 150 years ago?

Actually, those rivets can be either copper or brass ...depending on their pupose. Copper is more "bend-able" than brass -- therefore brass is stronger.

Brass or copper rivets generally aren't used to hold iron parts together. So, I suspect your iron object had rivets to attach it to something like leather, or perhaps wood.

CBG, wouldn't it have been nice to have attached to a wooden treasure chest! Thank you for your reply and explanation. Breezie

These look to be machine punched , but the problem is that Rivets have not change much in the last 200 years . We still use the same types . I guess it is if it is not broke don't fix it.

A lot of company's had gone to the lever crimp system other than ship or bridge builders who used hot rivets that where hammered . And this was back in the 1700's . I had to learn about these things in Engineering class .
But Breezie I am not a Rivet expert either so keep checking .

Are there any old sexnuts? LOL . . .. .I'm not going to Google that for fear of catching a virus . .or at least catching something! Thanks for your reply. Breezie

I noticed the slots. Dozer is correct. Common hammered rivets do not have a need for a slot.
