WASHER - SPLIT LOCK 1/4 (Mitsubishi MB1009454)

A damaged split lock washer can compromise fastener security in mechanical assemblies. During inspection, a split lock washer may show signs of flattening or cracking that reduce its locking ability. The split lock washer's plain mechanical function is to exert axial tension between a fastener head and the mating surface. A concrete generic failure consequence is that a worn split lock washer can allow a fastener to loosen under vibration. Keeping a split lock washer in sound condition helps maintain consistent clamping force in bolted joints. This aftermarket replacement part references Mitsubishi catalog number MB1009454.
