Common questions
How do I check the thread size?
This one is a 14x1.5 thread. Hold it next to a nut already on your vehicle or verify against the GM applications in the description above so the pitch and diameter match.
Why does seat type matter?
The nut's seat has to match your wheel's seat shape, since conical, ball, and mag seats are not interchangeable. Matching to your OEM-style hardware keeps the wheel centered and properly clamped.
