Fitment and specs

• Thread size: 12x1.25 (12mm stud, 1.25mm thread pitch)
• 6-spline tuner style drive, turns only with the included key
• Key head fits both 3/4 inch and 13/16 inch sockets
• Heat treated for extra strength
• Red finish
• Sold in 16, 20, or 24 piece sets, each with one key

Start all the nuts by hand, then tighten in a star pattern with the spline key and a torque wrench set to the spec in our torque reference chart. Skipping the impact gun on the final pass keeps the red finish looking new. Re-torque after 50 to 100 miles.

Common questions

How do I confirm these fit?
Match the thread first: your studs must be exactly 12x1.25, not 12x1.5. Then match the seat, since conical, mag, and ball seat wheels each take a different lug nut and the styles are not interchangeable. Send us your vehicle details if you want us to double check.

Do I get a key with every set?
Yes, the 16, 20, and 24 piece sets each include one spline key, and extra keys are available separately. The key is required for install and removal, so keep it with your spare tire tools.
