Value Collection L79NE2816-0813 Hex Lock Nut 1/2-13 316 Ss

Product Description

The VALUE COLLECTION L79NE2816-0813 is a 1/2-13 UNC hex lock nut with a nylon insert locking mechanism, manufactured from Grade 316 stainless steel with a bright uncoated finish. The nylon insert compresses against mating threads to resist vibration loosening without damaging the fastener or the threaded rod. At 19/32 inches in height and 3/4 inches across the flats, this nut meets standard dimensional requirements for 1/2-13 inch fastener assemblies. Grade 316 stainless steel provides elevated corrosion resistance compared to 304 grade, making it well suited for wet, marine, chemical, or outdoor environments. Licensed tradespeople working in plumbing, HVAC, pool equipment, and structural applications commonly specify this material grade where chloride or moisture exposure is a concern.

This hex lock nut is appropriate for use in residential and commercial applications where vibration, thermal cycling, or exposure to corrosive environments demands a reliable locking fastener. Typical installation scenarios include pump mounting hardware, pool and spa equipment frames, outdoor electrical enclosure assemblies, conduit support structures, and marine or coastal HVAC installations. The right-hand thread direction is standard for UNC fastener systems. This nut is sold individually with a minimum order quantity of 10 pieces per order.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chloride resistance
• Nylon insert locking style resists vibration-induced loosening without thread damage
• 1/2-13 UNC right-hand thread, compatible with standard inch-series fastener systems
• Bright uncoated finish — no coating to chip, flake, or interfere with torque values
• Width across flats of 3/4 inches accepts standard 3/4-inch combination or open-end wrenches
• Lightweight at 0.043 pounds per nut, practical for bulk fastener applications

Compatibility

Designed as an OEM-style replacement or standard-service hex lock nut for any 1/2-13 UNC threaded fastener assembly requiring a nylon insert locking nut in Grade 316 stainless steel.

Installation Notes

Installation is performed by hand-threading the nut onto a compatible 1/2-13 UNC bolt or stud, then tightening with a standard 3/4-inch wrench. De-energize or shut off any associated equipment before servicing fasteners in mechanical or electrical assemblies. Nylon insert lock nuts are generally considered single-use once fully seated, as the nylon deforms to the mating threads — inspect the insert before reuse in critical applications. Follow applicable mechanical or structural codes for torque requirements specific to your installation.
