LOCKWASHER (JLG JL91414012)

JL91414012: A damaged lockwasher can allow threaded fasteners to loosen under vibration, leading to joint failure. This aftermarket replacement part references the JLG catalog number JL91414012. 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 work surface. A common generic failure consequence is that a missing or worn lockwasher may cause the fastener to back off, resulting in component separation. Keeping a lockwasher in sound condition helps maintain clamping force in bolted assemblies. Verify the serial number or application, then call (562) 693-7748.
