The best aluminum 5/8 lug nut Ever Made! The original bearing washer lugnut by Mark Williams! MW bearing washer lug nuts integrate the nut and washer into one assembly. The integral washer spins freely, but will not separate from the nut, and prevents marring of the wheels and losing washers. Once you make the switch to Mark Williams 5/8" lugnuts, you'll never use another style again.
1/8" grip, threads relieved 1/8" on wheel side of nut. Sold each. The nut has a fixed counter bore depth that is equivalent to using the standard nut/washers combinations in the 1/8" thickness.

These are the best lug nuts. Light weight, spacer attached to the lug nuts and spins freely. Great product every vehicle i race will get a set.
