LOCKWASHER (Nissan NI28842-138)

A damaged lockwasher can allow threaded fasteners to loosen under vibration, leading to joint failure. During inspection, a lockwasher should be checked for deformation or cracking that reduces its spring tension. The lockwasher type provides a plain mechanical function by creating axial tension between the fastener and the mating surface. A concrete generic failure consequence is that a worn lockwasher may cause the fastener to back out, resulting in component separation. Keeping a lockwasher in sound condition helps maintain clamping force in bolted assemblies. This aftermarket replacement part references Nissan as the OE maker and cross-references part number NI28842-138. Verify the serial number or application, then call (562) 693-7748.
