not the sharpest knife in the drawer sometimes but i think they are used for what we call allen heads i bought them with some other tools at a pawn shop and what do ya'll think they are worth
Spark plug sockets for chainsaws, bikes, wheelers, snowmobiles, etc etc.
Insert screwdriver or round rod thru the hole for leverage. Most likely not worth much. I have a drawer full of them too.
you have some nice names on them so they look decent ones.
As stated above they are long reach sockets to be used with a screwdriver shaft or other bar which could fit sparkplugs of all kinds of stuff and other hard to reach bolts.
They look like they may have come from assorted different tool kits for older BMWs, MBs.... Very nice.
plumbers sockets
