WASHER (Nissan NI23200-72221)

A worn washer can allow fastener loosening under vibration, leading to component misalignment or mechanical noise. This aftermarket replacement part references Nissan catalog number NI23200-72221. The washer functions as a load-distributing spacer between a fastener head and the mating surface. Its plain mechanical role is to prevent galling and distribute clamping force evenly. A generic failure consequence is that a missing or crushed washer can cause the fastener to embed into the surface, reducing joint integrity. Keeping a washer in sound condition helps maintain consistent torque retention over time. Verify the serial number or application, then call (562) 693-7748.
