I suspect they may be for countersunk setting or for use on fixing reference or makers plates to machines etc. These have a slight taper and seem to comply with Wire/Numbered drill sizes of 49 and 43.- Would they have had a specific purpose?.

237 forum posts 135 photos	Hello Martin, Thanks, yes I would say they are harder than the usual iron clench rivets when closing with a small Ball Pein. The head diameters are 0.1250" and 0.1358". I suspect they are Plate Rivets as you say. Must be a use for them, as there are 1940 of the larger ones and 213 of the smaller size.

One seems to be off to one side wear while the other rippled along the taper section. They could possibly be also done during manufacture and normally discarded.

I'm guessing the 1940 ones were in a box of 2000 and you counted the 60 missing? pgk
