Frequently Asked Questions
Will these work with my factory wheels and aftermarket wheels?
M12 x 1.25 is a standard metric thread size. These fit any wheel that accepts M12 hardware — test-fit one nut before installing the full set to confirm clearance with your specific wheel.
Do I need a special key or tool to remove the lock ring?
The lock ring design isn't detailed in the product specs. When you receive them, the lug nut style will determine removal — standard wheel locks use a proprietary key, or they may be spline-drive. Verify with the included documentation or reach out to confirm before purchase.
How tight should I torque these?
Refer to your vehicle's service manual for the correct torque spec — it typically ranges based on your wheel and hub setup. Aluminum nuts follow the same spec as steel, but use a torque wrench to avoid over-tightening, which can strip the threads.
