Ultra Light King Pin Jam Nut

These aluminum jam nuts for king pins have all the strength you need at a fraction of the weight. The reduced hex design cuts weight and uses a smaller 3/4" wrench and has a 5/8"-18 thread. The extended washer allows for surface area to grip when tightened and prevents a wrench from scratching spindles. A pair of these weights approximately 1/10 of a pound less that standard steel jam nuts. Sold individually in raw aluminum.
