It’s time for another edition of Name This Tool here on Toolmonger. Photo pool member sheepslinky ran across this odd bolt, and he doesn’t know exactly what he’s got here. People have suggested it could be some sort of valve bolt or pin lock bolt, but it’s just guessing at this point — nothing definitive yet. We have to admit: we aren’t sure either.
So which one of you Toolmongers can school us in funky bolt identification? We’re looking for the name of the fastener and what it’s used for.
