http://www.plowcreek.org/temp/dscf3896s.jpgI got a collection of miscellaneous fasteners from a friend who moved away. These were in the collection. They are about 1/2" across. What are they used for?

Could they be buttons? Cheers, Tom

They look like Spokey Dokeys.

Ha! I knew I had seen them somewhere. Thanks Curlyben.

Thanks, Curlyben. Never heard of such a thing before. Must have lived a sheltered life back then. So, are they good for anything?

Yeah making an annoying rattling sound on your push bike.
Other than that, catapult ammo, maybe?

I ride a motor bike. Wouldn't it be neat if they lit up? Thanks, Ben

Curleyben-You are good!! No. D**n good!
