Will these work with my current wheels?

M12 x 1.25 is a common metric thread pitch. Check your wheel's lug hole specifications and your vehicle's hub to confirm thread match before purchase. If your wheels currently use a different thread pitch, these won't thread properly.

Do I need to prep or paint these before installing?

Aluminum lugs ship bare. If corrosion resistance matters in your climate, light anodizing or clear coating before install extends their life. Installation doesn't require prep, but clean the wheel hub threads first.

How tight should I torque these?

Refer to your vehicle's service manual for the correct torque specification—it varies by vehicle. The grooved shank helps distribute clamping force evenly, but proper torque prevents issues. Use a calibrated torque wrench and follow the star pattern when installing.
