Will these fit my wheels right out of the box?

The adapter is included, but verify your wheel stud configuration matches M12 x 1.5 specs before install. Check your vehicle's manual or existing lug nut thread size if unsure.

Do I need to prep or finish these nuts before installing?

Aluminum nuts arrive ready to use. Apply a small amount of anti-seize compound to studs before installation if you're in a high-corrosion environment—it extends the life of both nuts and studs.

What torque spec should I use?

Always refer to your vehicle's service manual for proper torque specification. Over-tightening aluminum nuts can strip the threads, so follow your manufacturer's recommendation exactly.
