Common questions
Will these fit if my current nuts are 9/16"?
They fit studs measuring 9/16 inch in diameter with 18 threads per inch. Test one on a stud by hand; it should spin on smoothly with no forcing. If you are unsure of your thread, compare a current lug nut or send us your vehicle details.
How many pieces should I order?
Multiply the studs on one wheel by your number of wheels. Five lug vehicles use 20, six lug use 24, and eight lug use 32, which matches the three set sizes offered here.
