5/8" Steel Wheel Stud Kit w/ Steel Lugnuts (1.75" shoulder) 51590

5/8 - 18 Steel Wheel Stud Kit w/ steel lugnuts

3.437" Overall Length/1.75" Shoulder Length

Mark Williams wheel studs and lugnuts are made in house. All studs start life as high strength steel alloy that is machined and then thread rolled for smooth, strong, and perfect threads. These studs are black oxide coated. Mark Williams lugnuts feature a two piece captured washer/bearing style design. This means no losing spacers or spacers that do not center. This creates a more even torque for the wheel along with convenience when dealing with hardware. 

Included:

• (10) 5/8-18 Steel Studs 3.437" overall length, 1.75" shoulder length
• (10) Steel Encapsulated Bearing Nuts (choose material in options)
• (10) Self Locking Jam Nut

Optional: Choose lugnut material in options

The steel axle drive stud is designed so the 11/16" diameter shoulder on the stud is used to center the wheel, rather than the lug nut used with smaller studs. This system dramatically increases shear strength and eliminates bent wheel studs. These studs require 5/8"-18 threaded holes in the axle flange. Drive studs are then secured in the flange with a jam nut.

Wheels are held in place with a steel bearing encapsulated lug nut with silver zinc plating. The integral aluminum washer snaps on to the nut and spins freely, but will not separate from the nut, preventing accidental loss. The nuts have washer thickness options of 31/6", 3/8", 9/16", 3/4" that make them equivalent to using a standard nut and washer combination of equal thickness.
