Castle NutThis castle nut is supplied as an aftermarket replacement, contact us to verify fit. Listed as nut - castle, it works within kingpin assemblies, tie rod ends, and steer axle linkages where a cotter pin retains torque, where dimensional accuracy and material grade decide whether a repair holds up to daily duty. Service technicians, fleet maintenance buyers, and resellers stock these as routine consumables on every forklift PM and repair job. Keeping it on hand turns a long downtime event into a quick swap on the shop floor, which is why dealers across Southern California source through SCR Forklift Parts in Whittier.
