Cleaning out the garage and I come across 7 lugnuts that have a funky swivel/pivet base on the back half (twice as long as a normal lug).

Anybody got a clue what they're for? I'd guess they're for pulling new studs thru axles and/or rotors?

Yeah, I know it's a stupid question, but I've never seen these things before. :flipoff2:

My 95 F350 has this type of lug nuts.

A picture might help....:skull:

I'll try and borrow the dig cam from work.
