Yeah, but it's missing the rubber bit.

Pretty sure there weren't any rubber bits as i found 20 of these in my garage and wasn't sure what car they came from.

Eh well mine have black rubber parts - like washers - anyway, they are what you suspect.

I know TJ-on the wheel nuts for Factory Alloys dont look like that, they have no taper, and an attached washer, can't comment on the thread, may suit steelies and Aftermarket alloys.

Rubber bit, if yours has rubber bits I would have them checked asap

The nut is off a second or third gen which runs steel rims

Dunno what they are off really and why i even have them lol
If anyone in VIC wants them they're yours

Carry a test nut with you everywhere you go and try it on every exposed thread you see until you come to a conclusion :hmm:
