NUT - LOCK (Yale YT220161722)

YT220161722: A damaged lock nut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, a lock nut resists rotation through a built-in mechanical feature, such as a nylon insert or deformed threads. The catalog reference is Yale part number YT220161722, an aftermarket replacement part. A common failure consequence is gradual fastener loosening, which may cause component misalignment or noise. Keeping a lock nut in sound condition helps maintain clamping force in threaded connections. Verify the serial number or application, then call (562) 693-7748.
