Circuit Performance Open Hex lug nuts for aftermarket wheels are cold forged for strength and plated for durability. The 6 sided hex design is an industry standard for its strength and resistance to stripping or breaking. The solid design ensures no rust will build up below the surface. The lug nut is 0.90″ wide, however please note that the socket used to install or remove the lug nut will wrap around the lug nut, and wheel compatibility will depend on the outside diameter of the socket. To ensure compatibility with your wheels, please compare the diameter of your socket to the size of the lug hole of the wheel you’ll be installing. This lug nut style works great on many factory and aftermarket wheels.
