Will these work with my aftermarket wheels?

M12 x 1.5 is the standard thread size for most modern vehicles. Check your wheel's lug hole diameter — 50mm acorn caps fit standard-depth holes on most aftermarket wheels. If your wheels have extra-deep pockets or use a different thread pitch, confirm before ordering.

Do the lock nuts work with aftermarket key covers?

These are the lock nuts themselves — they don't come with key-style covers. You'll pair them with your own locking lug nut covers or key set. Make sure your covers are sized for M12 x 1.5 lug nuts.

Should I clean or prep the studs before installation?

Wipe your wheel studs clean and dry before threading on the nuts. Dirt or corrosion on the studs can cause uneven seating. Hand-tighten first, then use a torque wrench to your vehicle's spec — do not over-torque aluminum nuts.
