Frequently Asked Questions
Will these fit my wheel studs without modification?
These are cut for M12 x 1.25 studs — verify your vehicle uses this metric size before ordering. If unsure, measure your current lug nut or check your service manual. Wrong thread pitch will not seat properly.
Can I reuse my existing wheels with these aluminum lug nuts?
Yes, aluminum lug nuts work with all standard wheels. The closed-end design may sit slightly different than OEM open-end nuts, but they clamp identically. Test-fit one wheel before installing all four.
Do I need to torque these to a specific value?
Refer to your vehicle's service manual for the correct torque specification — aluminum lug nuts tighten to the same spec as OEM steel hardware. Over-torquing can strip the aluminum, so use a calibrated wrench or torque stick.
