I've had these for 30+ years, just hanging around in the bottom drawer of a
old, narrow set of drawers I brought home from a dead relative's shop.

The whole batch weighs just over 1/2 lb. I'm guessing aluminum.

They were found in a drawer with curved bottomed sections. The drawers must
have been modified. Only 2 of the 8 have the curves and it looks like they
had straight dividers at some time.

I wonder why those curved bottoms were added.



I used rivets like this in shop class, in 1969.

You drill a hole through pieces of metal to be attached with a rivet.

You slide the rivet through the holes, round end sits on an anvil with a
cupped indention that matches the shape of the rivet.

You take a large ball peen hammer and whack the rivet until the end
flares out and captures the pieces of metal.

I do not recall the name of the tool, but you place a hand held tool,
with a similar indentation as the anvil, over the end you just finished
hammering and give it a couple of blows to form a finished look to the
end of the rivet.
Still use the aluminum solid rivets building aircraft today. Hammer
and bucking bar. Need to cut the rivets to accurate length for the
"grip" required.
