Common questions
What does 12x1.25 mean?
12 mm is the stud diameter and 1.25 mm is the thread pitch, the distance between threads. Both numbers have to match your studs exactly; check your current lug nuts or owner's manual before ordering.
Do these replace all my lug nuts?
No. The set of 4 puts one lock on each wheel while your remaining standard lug nuts stay in place. One lock per wheel is enough to stop a wheel from coming off without the key.
