Do I need a special socket or tool to install these locking nuts?

You'll need the included key to remove the 4 locking nuts. Standard socket sizes work for installation and removal of the regular nuts — just use the key for the locking pieces when needed.

Will these work on my current wheel studs?

These are M12x1.5 metric thread. Verify your vehicle uses M12x1.5 studs before ordering — if you're unsure, check your owner's manual or measure an existing lug nut. Mismatched threads won't seat properly.

Can I use these with my aftermarket wheels?

Yes, as long as the wheel has standard M12x1.5 lug holes and your studs are M12x1.5. Aftermarket wheels typically use the same thread spec, but confirm your wheel specs match before installation.
