LOCKWASHER (Toyota TY0302-0005)

TY0302-0005: A damaged lockwasher can allow threaded fasteners to loosen under vibration, leading to joint failure. This aftermarket replacement part references Toyota catalog number TY0302-0005. A lockwasher is a type of hardware washer that creates tension between a nut and a mating surface. Its plain mechanical function is to resist rotational loosening by biting into the fastener and the workpiece. A concrete generic failure consequence is that a missing or worn lockwasher may cause a bolted connection to back off over time. During routine service, a lockwasher that has lost its spring tension should be replaced to maintain clamping force. Verify the serial number or application, then call (562) 693-7748.
