Look at the attached photo and tell me what the heck this is for. I put the quarter next to it for a size perspective.
I got it in a pile of sockets from Robins AFB.
On the side of the socket it has stamped" NIM 4751 U.S.A."
It came from some sort of avionics shop that was shut down a couple of years ago.

It appears, to me at least, to be a key for a locking lugnut.

Yea, but it's a 1/4" drive socket. And it's almost smaller than the quarter next to it. Have to be a pretty small lug nut.
Thanks for playin' tho.
I really have no idea what it's for.

:dunno:
 
Looks like one I have seen to unscrew the wormgear hose clamps that have a 'tab' instead of a 5/16" bolt head or a screwdriver head. Not sure why four fllutes are necessary though.
 
I think Nick might be on the right track, i think its a socket for tamper proof nuts. But what do i know. If you find out let us know, maybe i'll call me buddy that has a radio shop and see if he knows.

It looks like something you'd use to torque a castellated nut and while pressure is still applied, slip the pin in. I'm thinking some kind of spring loaded assembly. WAG

I believe we have a winner. I've used a socket just like that during my last annual to tighten the thumb screws on the hose clamps for the intake runners.

Thanks, Mark.
It makes sense to me now that I think about it. What with aviation having a torque spec for everything the only way to get a proper tightness per a torque sheet on a clamp like that would be to use a torque wrench and this would let you do that.
:yes:
 
Hey Keith. Next time please use a document with more than just your address & phone number as your back drop. A social & mother's maiden name would be great. Thank you :) :goofy: :) :goofy:
