Frequently Asked Questions
Will these fit my current wheels?
M12 x 1.25 is a common thread pitch, but seat profile and extension length vary by wheel design. Measure your current lug nut length and compare to these extended nuts before ordering — spline drive requires the correct seat engagement to function properly.
Do I need special tools to install these?
A 19mm or 21mm socket (depending on your nut head size) and a ratchet handle the installation. The spline drive design is straightforward — no impact gun required, though one works fine if you're swapping multiple wheels.
How tight should I torque them?
Refer to your vehicle's service manual for the correct torque specification — it varies by make and model. Over-torquing aluminum nuts can strip threads; under-torquing risks loosening. Once set, the lock feature prevents vibration-induced rotation.
