Will these work with my stock wheels and aftermarket wheels?

Grooved shank lug nuts fit any wheel with a standard conical seat. They're designed to work across both stock and custom wheel setups without modification.

Do I need to use threadlocker or anti-seize with these?

Not required, but threadlocker is common practice for track use or high-vibration environments. Apply sparingly to the threads before installation if you choose to use it.

How tight should I torque these?

Refer to your vehicle's service manual for the correct torque spec—it varies by platform. Tighten evenly in a star pattern to avoid wheel runout.
