Common questions
Will these fit my vehicle?
They use 1/2"-20 threads and are a common fitment on older GM and Chrysler cars and trucks. Check your stud thread size first; the thread has to match exactly for the nut to install safely.
Can I use them on mag or ball seat wheels?
No. These are bulge acorn nuts with a tapered conical seat, and seat styles are not interchangeable. Use them only on wheels machined for a conical seat.
