WASHER - LOCK (Nissan NI01602-20825)

NI01602-20825: A damaged lock washer can allow threaded fasteners to loosen under vibration, leading to component separation or misalignment. During assembly, a lock washer’s spring tension resists rotational loosening of nuts and bolts. This aftermarket replacement part references Nissan catalog number NI01602-20825. The washer type provides a plain mechanical function by creating friction between the fastener head and the mating surface. A generic failure consequence is that a worn or missing lock washer may cause the fastener to back out, resulting in mechanical play or part detachment. Keeping a lock washer in sound condition helps maintain clamping force in bolted joints. Verify the serial number or application, then call (562) 693-7748.
