Frequently Asked Questions
Do these lock nuts need to be torqued to a specific value?
Refer to your vehicle's service manual for the correct torque specification for M12 fasteners. The lock design engages during normal tightening — no special procedure required.
Will these work with my aftermarket wheels and spacers?
L40 length is designed for extended applications like thick spacers and deep-dish wheels. Measure your hub surface to the wheel mounting face to confirm clearance before installation.
Can I use these as a direct replacement for my stock lug nuts?
Thread size and pitch are M12 x 1.25 — verify your vehicle uses this specification before purchase. If your factory nuts are a different size, these will not fit.
