Industrial BUS31FK1414 7 8-14 FIN JAM FLX LK NUT C Lock Nut

The BUS31FK1414 7/8-14 thin jam lock nut is a steel hex jam nut (thin profile) that mechanically locks threaded fasteners to resist loosening under vibration and load in industrial equipment. Designed for 7/8-14 UNF threads with a reduced thickness, it serves as a locking element in mechanical joints across industrial machinery, hydraulic systems, motor mounts, conveyors, and heavy equipment in continuous-duty manufacturing environments. This OEM / Industrial Fastener part is offered in zinc-plated or plain finishes and employs jam nut friction locking against a mating nut to secure bolted assemblies (MPN BUS31FK1414).
