Common questions
Will these work with my wheels?
The nut seat has to match the wheel seat. Acorn style nuts use a tapered seat, and tapered, mag, and ball seats are not interchangeable, so check the lug holes on your wheels before ordering.
How do I confirm 1/2"-20 is my thread size?
1/2"-20 means a 1/2" stud diameter with 20 threads per inch, a size found on older GM and Chrysler vehicles. If one of your current lug nuts threads onto a stud smoothly by hand and matches this size, you are set.
