NUT - LOCK (Crown CR73553-002)

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 locking feature, such as a nylon insert or deformed threads. The catalog reference for this aftermarket replacement part is Crown part number CR73553-002. Its general function is to fasten components by threading onto a bolt or stud. A common failure consequence is that a worn lock nut may not maintain clamping force, allowing the joint to separate. Keeping a lock nut in sound condition helps prevent unexpected disassembly of attached parts. Verify the serial number or application, then call (562) 693-7748.
