NUT - LOCK (Yale YT200077690)

A damaged lock nut can compromise the security of a bolted joint, leading to loosening under vibration. During inspection, a lock nut may show signs of thread wear or deformation that reduces its locking ability. This aftermarket replacement part is cataloged under Yale part number YT200077690. The nut's primary function is to resist loosening through a mechanical locking feature, such as a deformed thread or nylon insert. A common failure consequence is gradual fastener back-out, which can allow connected components to separate. Keeping a lock nut in sound condition helps maintain clamp load in threaded assemblies. Verify the serial number or application, then call (562) 693-7748.
