NUT - NYL LOCK (JLG JL1001265147)

JL1001265147: A damaged lock nut can allow fastened components to loosen during operation, leading to mechanical misalignment or failure. The JLG catalog reference for this aftermarket replacement part is JL1001265147, a nylon-insert lock nut. Its plain mechanical function is to resist self-loosening under vibration by creating friction on the threads. A concrete generic failure consequence is that a loose nut may cause bolted joints to separate, risking equipment damage. Keeping a lock nut in sound condition helps maintain secure fastening in threaded assemblies. Verify the serial number or application, then call (562) 693-7748.
