Common questions
Do these need to match my wheel's seat type?
Yes. Conical, mag, and ball seat lug nuts are not interchangeable. A mismatched seat will not clamp the wheel correctly no matter how tight it feels, so confirm what your wheels are drilled for before ordering.
How many should I order?
These are priced per piece, so order one for each wheel stud on your vehicle. Many buyers add a spare or two to the same order.
