Castle NutThis castle nut is an aftermarket replacement part stocked by SCR Forklift Parts for material handling service providers who need a dependable substitute without sourcing through an OEM dealer. It is commonly used on general fastening across mast, frame, steer axle, and counterweight assemblies, where worn or damaged hardware needs swapping during routine PM or breakdown repair. Keeping pieces like this on the shelf shortens downtime, since hardware failures often halt a lift truck mid-shift.
