Common questions
What does 12x1.25 mean?
It describes the thread: 12mm stud diameter with a 1.25mm thread pitch. Match it to your wheel studs before ordering. A correctly matched nut spins on smoothly by hand, while forcing the wrong pitch will damage the stud threads.
Can I use these on wheels made for conical, mag, or ball seat nuts?
No. Seat types are not interchangeable. These are ET style nuts with conical washers made for old style E-T wheels, and other wheel seats need their own matching nut style to sit flat and hold torque.
