Will these work with my aftermarket wheels?

These are M12 x 1.25 fitment — confirm your wheel bolt pattern matches before ordering. The acorn design works with most modern wheels that accept domed lug nuts, but deep-dish or ultra-thin designs may need clearance verification.

Do I need a special socket to install these?

Standard acorn nut sockets work fine. If you don't have one, they're cheap and worth keeping in your kit — beats stripping out a lug nut with the wrong tool.

How do the locking nuts actually work?

The locking portion uses internal gripping to bite into the stud threads and resist vibration. Install them the same way as regular lugs — they'll hold tighter the more they're torqued down. Tighten to your vehicle's specified torque spec.
