Frequently Asked Questions
Will these work with my current wheel studs?
M12 x 1.25 is the standard fitment for most applications, but verify your vehicle's stud size before ordering. If your studs are M14 or a different pitch, these won't thread on.
Do I need a special socket to install these?
Use a standard 19mm lug nut socket—same as OEM. Tighten according to your vehicle service manual; don't over-torque aluminum nuts on steel studs.
Can I mix these with my existing lug nuts?
You can use them alongside other nuts, but all five on one wheel should match to keep torque load even. Mismatched hardware on a single wheel can cause vibration and loosening.
