QU40004 Spindle Nut fits spindles with thread diameters of 1-5/8".
The pin that protrudes from the outboard face is an anti-rotation device that engages with one of the holes in either QU40060 or QU40429 Spindle Lock Washers. Installing the lock washer without having the pin engage one of the holes will either break or bend the pin. Improperly installed nuts and washer sets can back off during vehicle operation and possibly cause the hub and wheel assembly to fall off which may lead to severe injury or death.
