WASHER - LOCK (JLG JL4762000-100)

JL4762000-100: A damaged lock washer can allow threaded fasteners to loosen under vibration. During assembly, a lock washer resists rotational loosening by embedding its edges into the mating surface. The catalog reference is JLG, and the aftermarket replacement part number is JL4762000-100. This hardware washer type provides a plain mechanical function of increasing friction between the fastener head and the joint. A common failure consequence is that a missing or worn lock washer leads to fastener back-out and joint separation. Keeping a lock washer in sound condition helps maintain clamp load in bolted connections. Verify the serial number or application, then call (562) 693-7748.
