LOCKWASHER (Toyota TY03020-010)

TY03020-010: A damaged lockwasher can allow threaded fasteners to loosen under vibration. This aftermarket replacement part references Toyota catalog number TY03020-010. 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 joint. A concrete generic failure consequence is that a missing or worn lockwasher can lead to fastener back-out and joint separation. During routine service, a lockwasher may be replaced whenever a fastener is removed and reinstalled. Verify the serial number or application, then call (562) 693-7748.
