Do these lug nuts work on my wheels without modification?

Thread size is M12x1.5 — verify your wheel studs match before purchase. The adapter included gives you flexibility, but you'll need to confirm fitment to your specific studs. Test-fit one nut before committing to the full set.

How tight should I torque these?

Refer to your vehicle's service manual for the correct torque specification. Aluminum lug nuts require the same torque value as steel, but don't overtighten—aluminum can strip if crushed against the wheel seat.

Will these need painting or any prep before installation?

They ship polished silver and ready to install. If you prefer a different finish, you can paint or powder-coat them, but prep the surface lightly first to ensure adhesion.
