Common questions
How do I confirm 12x1.75 is the right thread?
Match it against one of the lug nuts you are removing. Thread pitch has to match exactly, and a nut that binds after a turn or two is the wrong pitch and should never be forced.
Do these fit any wheel seat?
No lug nut does. Conical, mag, and ball seats are not interchangeable, so verify the seat style machined into your wheels before installing, and ask us if you are not certain what you have.
