Value Collection MPC712203 Hex Lock Nut 5/16-24 50 Pack

Product Description

The VALUE COLLECTION MPC712203 is a 5/16-24 UNF hex lock nut with a distorted-thread locking style, designed to resist loosening under vibration and dynamic loads without requiring a separate locking element. The nut is manufactured from Grade B steel with a zinc-plated and wax-plated finish that provides corrosion resistance and reduces installation torque. At 17/64 inches high with 1/2 inch across the flats, this is a standard-profile hex nut suited for general mechanical and structural fastening applications. Each package contains 50 nuts. Licensed tradespeople and maintenance professionals working on equipment assemblies, bracket mounting, and general mechanical fastening will find this a practical shop-stock item.

This hex lock nut is appropriate for use in residential, commercial, and light industrial mechanical assemblies wherever a 5/16-24 UNF right-hand thread fastener is required. The distorted-thread design creates prevailing torque through thread interference, making it reusable for low-cycle service. Typical applications include HVAC equipment panels, electrical enclosure mounting hardware, plumbing fixture brackets, and general equipment assembly where vibration resistance is needed without adhesive thread-locking compounds. Packaged in a quantity of 50, this part is well suited for bench stock and service van inventory.

Key Features

Compatibility

Designed as an OEM-style replacement or service fastener for any mechanical assembly requiring a 5/16-24 UNF hex lock nut with a distorted-thread prevailing-torque design.

Installation Notes

Installation is performed by qualified maintenance technicians or tradespeople using a 1/2-inch wrench or socket. Power down and de-energize any equipment before replacing fasteners on electrical or mechanical assemblies. Distorted-thread lock nuts may be reused for low-cycle applications but should be inspected for thread damage before reuse. Follow applicable torque specifications from the equipment manufacturer or relevant codes such as the NEC or IFGC when fastening components in regulated systems.
