Value Collection MPC712200 Hex Lock Nut 1/4-20 50 Pack

Product Description

The VALUE COLLECTION MPC712200 is a 1/4-20 hex lock nut with a distorted-thread locking style, designed to resist loosening under vibration and torque loads without requiring a separate locking insert or adhesive. Manufactured from Grade B steel with a zinc-plated and wax-plated finish, this nut provides corrosion resistance and smooth installation in threaded assemblies. The nut measures 7/32 inches in height with a 7/16-inch width across flats and features a right-hand UNC thread. It is suited for mechanical, HVAC, plumbing, and electrical panel work where a secure, reusable fastener is required.

This hex lock nut is appropriate for a wide range of trade applications including equipment mounting, bracket assembly, and panel fabrication in both residential and light commercial environments. The distorted-thread design allows the nut to be used on standard UNC 1/4-20 threaded fasteners and does not require special tooling for installation. Sold in a package quantity of 50, it is well suited for service technicians and contractors who need reliable fasteners in volume for recurring work orders or stocked field kits.

Compatibility

Designed as an OEM-style replacement or service fastener for any assembly using 1/4-20 UNC right-hand threaded bolts or studs requiring a locking hex nut.

Installation Notes

Installation requires a standard 7/16-inch hex wrench or socket. Power down or de-energize any equipment before accessing fastened assemblies on electrical or HVAC components. Distorted-thread lock nuts may be reused a limited number of times before the locking torque diminishes; inspect the nut for thread deformation before reuse in critical applications. Follow applicable mechanical and electrical codes for fastener torque requirements specific to the assembly.
