WASHER - LOCK (Mitsubishi MB089152461A)

MB089152461A: A damaged lock washer can allow threaded fasteners to loosen under vibration, leading to joint failure. During assembly, a lock washer resists rotational loosening by embedding its edges into the mating surfaces. Keeping a lock washer in sound condition helps maintain clamping force in bolted connections. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB089152461A. The washer type provides a plain mechanical function of preventing fastener back-out. A concrete generic failure consequence is that a missing or worn lock washer may cause bolted components to separate. Verify the serial number or application, then call (562) 693-7748.
