Common questions

What does open end mean?
The top of the nut is open, so the wheel stud can pass through instead of bottoming out inside a closed cap. That makes open end nuts a practical choice when your studs sit longer than a closed style would allow.

Will these match my wheels?
Confirm two things: the 1/2" thread must match your studs, and the nut seat must match the seat your wheels are machined for. Conical, mag, and ball seats are not interchangeable, so send us your wheel details if you are unsure.
