Value Collection 30637 Hex Lock Nut 7/16-14 316 Ss 25-pack

Product Description

The VALUE COLLECTION 30637 is a 7/16-14 UNC hex lock nut with a nylon insert locking mechanism, manufactured from Grade 316 stainless steel. The nylon insert grips the mating thread and resists loosening under vibration, thermal cycling, and dynamic loading. At 29/64 inches in height and 5/8 inches across the flats, this nut fits standard 7/16-14 fastener assemblies. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making it a reliable choice in wet, chemical, or marine environments. Right-hand thread direction follows standard UNC convention. Each package contains 25 nuts.

These hex lock nuts are suited for plumbing, HVAC, marine, and industrial applications where moisture, salt spray, or chemical exposure is a concern. The nylon insert style is common in equipment assemblies, pipe supports, conduit mounting, and mechanical connections that experience vibration or frequent thermal changes. Installers in commercial and residential mechanical trades use this fastener type when a positive locking solution is required without thread-locking compounds.

Key Features

• Nylon insert locking style resists loosening under vibration and thermal cycling
• Grade 316 stainless steel construction for corrosion resistance in harsh or wet environments
• 7/16-14 UNC thread size with right-hand thread direction
• Height of 29/64 inches and 5/8 inches across the flats for standard wrench fitment

Compatibility

Designed as a standard UNC replacement or new-installation hex lock nut for any 7/16-14 threaded fastener application requiring a nylon insert locking style.

Installation Notes

Installation requires a standard open-end or combination wrench sized to 5/8 inches across the flats. De-energize or depressurize any system before replacing fasteners in live assemblies. Nylon insert lock nuts are generally intended for single-use applications; inspect the nylon insert before reuse, as repeated cycling can reduce locking torque. Follow applicable mechanical and structural codes for the specific trade application.
