Will these fit my stock wheels?

M14 x 1.5 is the most common thread pitch for most vehicles. Confirm your wheel bolt pattern and thread size before ordering — measure an existing lug nut or check your owner's manual to be certain.

Do I need anything else to install these?

You'll need a socket that fits the 23mm head and your vehicle's lug nut wrench or impact gun. The lock key comes in the box; just swap your old nuts for the new ones and torque to your vehicle's spec.

How does the lock key actually work?

One of the 24 nuts has a special locking collar. The lock key slides over that collar and prevents it from turning without the key — it stays with your vehicle so only you can remove the wheels.
