Bullet nose design allows for fastest wheel changes by aligning the nut parallel to threads while pushing the nut onto the stud with an impact gun. Rounded nose reduces missed attempts and reduces damage to nut threads.

Conical, or "cone nuts" use a 60° taper on them and are popular with most aftermarket wheels, most racing wheels and many OE wheels as well. Available for 12 & 14mm studs.
Spherical, or ball seat nuts have a radius ground into them to match the OEM wheel nut/bolt on cars such as VW, Audi and Porsche. It is very important to match the radius of your OE type wheel seats with the proper radius nuts.

Copper Coated racing wheel nuts from ACS. The thin copper coating provides an anti-seize surface for use in even the most demanding endurance environments. The coating also "bites" the wheel seats & threads preventing nuts from loosening on track. Used by professional race teams.

We also offer ARP press in racing studs for popular makes such as Subaru, Porsche and Honda.
