PIN - COTTER (Nissan NI00921-43500)

NI00921-43500: A damaged cotter pin can lead to fastener loosening and component separation during operation. This aftermarket replacement part references Nissan as the OE maker and cross-references part number NI00921-43500. The cotter pin is a hardware pin type used to secure clevis pins or threaded fasteners by passing through a hole and having its legs spread. A common failure consequence is that a missing or broken cotter pin allows the retained part to shift or detach, causing mechanical misalignment or sudden disassembly. In a typical usage context, cotter pins are installed in applications where vibration or movement could otherwise back out a nut or pin. Verify the serial number or application, then call (562) 693-7748.
