Will these work with my current wheel studs?

M12 x 1.5 is a common metric size. Verify your vehicle's stud size before ordering — if your studs are SAE (like 7/16-20), these won't thread on. Check your manual or measure an existing lug nut.

Do I need to apply thread-locking compound?

The integrated lock design resists loosening from normal vibration. Most buyers skip additional compounds, but adding a drop of removable thread-locker (blue formula) gives extra insurance if you frequently remove wheels.

How tight should I torque these?

Refer to your vehicle's service manual for the correct torque spec — it varies by vehicle weight and suspension. Using a calibrated torque wrench prevents over-tightening, which can strip the aluminum.
