Value Collection R50000016 Hex Lock Nut 7/16-20

Product Description

The VALUE COLLECTION R50000016 is a 7/16-20 UNF hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert creates prevailing torque by deforming around mating threads, resisting loosening from vibration and movement without requiring adhesives or secondary locking devices. Standing 15/32 inches high with a 5/8-inch width across flats, this fastener is sized for standard hex tooling. Right-hand thread direction conforms to UNF standards. It is used across HVAC, plumbing, electrical, and mechanical assembly applications wherever a reliable, reusable locking fastener is required.

This nut is suited for general mechanical assemblies, HVAC equipment mounting, electrical enclosure hardware, and plumbing fixture installations that call for a 7/16-20 UNF thread. The zinc plating provides basic corrosion resistance for indoor and protected outdoor environments. Installers in residential and light commercial settings will find this nut compatible with standard 7/16-inch bolts and studs in a wide range of trade applications. Minimum order quantity is 100 units per order.

Key Features

• Nylon insert locking style resists loosening under vibration without thread-locking compounds
• 7/16-20 UNF right-hand thread for compatibility with standard inch-series fasteners
• Grade 2 steel construction balances adequate strength with cost efficiency for general-purpose use
• Zinc-plated finish offers basic corrosion resistance in protected environments
• 15/32-inch height and 5/8-inch width across flats fit standard hex wrench and socket tooling

Compatibility

Designed as a general-purpose replacement or stock fastener for any assembly requiring a 7/16-20 UNF hex lock nut with nylon insert locking.

Installation Notes

Installation is performed with a standard hex wrench or socket sized to 5/8 inch across flats. As with all nylon insert lock nuts, the nut should be run down by hand until the nylon insert engages the bolt threads before applying torque with a tool. Nylon insert lock nuts are rated for single or limited reuse — inspect the nylon insert for damage before reusing. Follow applicable mechanical or trade codes for fastener torque requirements specific to your assembly.
