Value Collection MPC712206 7/16-14 Hex Lock Nut 25 Pack

Product Description

The VALUE COLLECTION MPC712206 is a 7/16-14 UNC Grade B hex lock nut with a distorted thread locking mechanism, sold in a pack of 25. Distorted thread lock nuts resist loosening under vibration and dynamic loads by creating mechanical interference between the nut threads and the mating fastener — no secondary locking hardware required. Constructed from steel with a zinc wax plated finish, this nut is suited for general mechanical and structural fastening applications where reliable thread retention is required. The 11/16-inch width across flats is compatible with standard hex tooling.

These hex lock nuts are used across a broad range of trade and industrial applications, including HVAC equipment assembly, mechanical room piping supports, electrical enclosure mounting, and structural bracketing. The distorted thread design makes them a practical choice in any installation where vibration or thermal cycling could compromise a standard nut. The pack quantity of 25 supports both single-job use and bench stock replenishment for service technicians and contractors.

Key Features

• Distorted thread locking design resists loosening under vibration without additional lock washers or adhesives
• 7/16-14 UNC thread specification for compatibility with standard unified coarse thread fasteners
• Grade B classification for general-purpose fastening applications
• Steel construction with zinc wax plated finish for corrosion resistance
• 11/16-inch width across flats fits standard hex sockets and wrenches
• 25-piece pack quantity supports job-site and bench stock use

Compatibility

Designed for use with 7/16-14 UNC externally threaded fasteners in general mechanical, structural, and equipment-mounting applications.

Installation Notes

Installation is appropriate for mechanics, HVAC technicians, plumbers, and electricians performing equipment assembly or structural fastening work. Use a standard 11/16-inch hex socket or open-end wrench to drive the nut to the required torque for the application per the relevant equipment manufacturer specification or applicable code. Distorted thread lock nuts are typically single-use — once removed, the locking force may be reduced, and replacement is recommended for critical joints. Always de-energize or shut down equipment before servicing fastened assemblies on live systems.
