Thread each nut on by hand before reaching for tools, then tighten in a star pattern and finish with a torque wrench set to the spec in our torque reference chart. Hand torquing on the final pass protects the chrome plating. Re-torque after the first 50 to 100 miles.

Common questions

Will these fit my wheels and studs?
Your studs must be threaded exactly 12x1.25, and your wheels' seat type must match the nut, since conical, mag, and ball seats are not interchangeable. The open end also lets longer or extended studs pass straight through without bottoming out.

Can I install these with a regular socket?
No. The 6-spline drive only turns with the included key. Slip the key over the nut, then drive it with a 3/4 inch or 13/16 inch socket or wrench. Keep the key in the car for roadside tire changes, and add a spare key to your order if you want backup.
