WASHER (Nissan NI22511-02011)

A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references Nissan as the OE maker and cross-references part number NI22511-02011. The washer functions as a load-distributing spacer placed under a fastener head or nut. Its plain mechanical role is to prevent galling and distribute preload evenly across the mating surface. A generic failure consequence is that a missing or crushed washer may allow fastener relaxation, causing vibration-induced separation. During routine service, a washer that is deformed or corroded should be replaced to maintain joint integrity. Verify the serial number or application, then call (562) 693-7748.
