Value Collection R50000023 Hex Lock Nut 7/16-14

Product Description

The VALUE COLLECTION R50000023 is a 7/16-14 UNC hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert deforms around the mating thread when the nut is driven down, creating friction that resists loosening under vibration and thermal cycling. At 21/64 inches high and 11/16 inches across the flats, this is a standard-profile prevailing-torque fastener suited for general mechanical assemblies. Right-hand thread direction conforms to UNC standards. Licensed trades and maintenance technicians use this style of nut wherever a secondary locking feature is required without adhesive thread-locking compounds.

This hex lock nut is used in general industrial, HVAC, plumbing, and mechanical applications that call for a 7/16-14 UNC threaded fastener with vibration-resistant retention. It is appropriate for light-to-medium structural connections in equipment frames, panel mounts, pipe support brackets, and similar assemblies where the joint may experience movement or vibration during service. The zinc-plated finish provides a baseline level of corrosion resistance suitable for indoor and sheltered outdoor environments.

Key Features

• Nylon insert provides prevailing-torque locking without thread-locking compound
• 7/16-14 UNC right-hand thread for broad fastener compatibility
• Grade 2 steel construction for general-purpose load requirements
• Zinc-plated finish for corrosion resistance in typical service environments
• 21/64 inches height fits standard hex nut tooling and clearance envelopes
• 11/16 inches across flats accepts standard open-end and socket wrenches

Compatibility

Designed as a direct replacement or supplementary fastener for any assembly requiring a 7/16-14 UNC hex lock nut with nylon insert in Grade 2 steel.

Installation Notes

Installation requires a standard 11/16-inch open-end, box-end, or socket wrench. Power down or de-energize any equipment before accessing fastener locations on electrical or HVAC assemblies. Nylon insert lock nuts are single-use by design — the locking torque of the insert degrades after removal, and the nut should be replaced rather than reused. Follow applicable mechanical and structural codes for torque requirements specific to the assembly being serviced.
