Value Collection L79NE2816-0616 Hex Lock Nut 3/8-16 316 Ss

Product Description

The VALUE COLLECTION L79NE2816-0616 is a 3/8-16 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 loosening caused by vibration, thermal cycling, and dynamic loads. At 29/64 inches high with a 9/16 inch width across flats, this fastener is sized for standard 3/8-16 threaded assemblies. Grade 316 stainless steel provides elevated corrosion resistance compared to 304, making it a preferred choice for marine, chemical processing, pool equipment, and outdoor plumbing applications. Right-hand thread direction follows standard UNC convention. Installation and removal require a standard 9/16 inch wrench or socket.

This nut is suited for residential and commercial applications where vibration resistance and corrosion resistance are both required. Common use cases include pool and spa equipment assemblies, marine hardware, HVAC equipment mounting hardware, plumbing fixtures, and any outdoor or wet-environment structural fastening. The nylon insert provides a prevailing-torque locking action without the need for thread-locking compounds, making it practical for assemblies that require periodic disassembly. Installers working in coastal, chemical, or chlorinated environments will find the Grade 316 alloy appropriate for extended service life.

Key Features

• Nylon insert locking style resists loosening from vibration and thermal cycling without adhesives
• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 3/8-16 UNC right-hand thread for compatibility with standard inch-series threaded fasteners
• Bright uncoated finish — no coating to flake, chip, or interfere with torque values
• 29/64 inch height and 9/16 inch width across flats fit standard hex tooling

Compatibility

Designed for use with 3/8-16 UNC right-hand threaded bolts, studs, and threaded rod in inch-series fastener assemblies.

Installation Notes

Install using a 9/16 inch open-end wrench, box wrench, or socket. Because the nylon insert provides prevailing-torque resistance, slightly higher installation torque is normal compared to a standard hex nut. Nylon insert lock nuts are generally rated for single use — once the nylon has been fully engaged and the nut removed, inspect the insert before reuse. Do not use impact drivers at high torque settings, as excessive force can damage the nylon insert and eliminate the locking function.
