Do these work with my factory wheels?

M12 x 1.25 is the standard metric thread for most wheels. Confirm your wheel's lug hole spec before ordering — if your factory wheels use a different thread pitch or seat type, these won't fit.

Are the locking nuts keyed, or how do the locks work?

Four nuts in this set have a locking feature to prevent removal — exact locking mechanism not specified. Test the fit on your wheels before installation to ensure compatibility with your wheel's internal diameter.

What torque spec should I use to install these?

Always refer to your vehicle's service manual for lug nut torque specs — using too much force can strip the threads or crack your wheels. Torque specs vary by vehicle, not by the nut itself.
