LOCKWASHER (Nissan NI01602-21441)

A damaged lockwasher can allow threaded fasteners to loosen under vibration, leading to component separation or misalignment. The catalog reference for this aftermarket replacement part is Nissan, with cross-reference number NI01602-21441. A lockwasher is a type of hardware washer that provides a spring-like tension between a fastener and its mating surface. Its plain mechanical function is to resist rotational loosening by biting into the fastener head and the work surface. A concrete generic failure consequence is that a missing or worn lockwasher may cause the fastener to back out, resulting in rattling or detachment of secured parts. During routine service, a lockwasher should be replaced if it appears flattened or cracked. Verify the serial number or application, then call (562) 693-7748.
