Value Collection CLNFI20870-025BX Hex Lock Nut 7/8-14

Product Description

The VALUE COLLECTION CLNFI20870-025BX is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this two-way lock nut uses a mechanically deformed thread form to create prevailing torque without secondary locking elements. The 7/8-14 UNF thread is right-hand direction. At 0.75 inches high with a 1-5/16-inch width across flats, this fastener fits standard hex tooling. It is installed by licensed trades and general contractors in mechanical assemblies, structural connections, and equipment mounting applications where fastener retention is required.

This hex lock nut is suited for residential and commercial mechanical installations where vibration or cyclical loading could cause a standard nut to back off. Typical applications include HVAC equipment mounting, plumbing fixture framing, electrical enclosure assembly, and general structural fastening using UNF-threaded rod or bolt stock. The distorted-thread locking style does not require a nylon insert, making it suitable for higher-temperature environments where nylon-insert lock nuts are not appropriate.

Key Features

• Distorted-thread (two-way) locking style provides prevailing torque without secondary components
• 7/8-14 UNF right-hand thread for compatibility with standard inch-series fastener systems
• Grade 2 steel construction suitable for general-purpose mechanical fastening
• Zinc-plated finish for basic corrosion and oxidation resistance
• 0.75-inch height and 1-5/16-inch width across flats fits standard hex wrenches and sockets
• No nylon insert — appropriate for moderate-temperature service environments

Compatibility

Designed as a general-purpose replacement or stock fastener for any assembly using 7/8-14 UNF right-hand threaded bolt or rod stock conforming to inch-series fastener standards.

Installation Notes

Install using a standard hex wrench or socket sized for a 1-5/16-inch width across flats. De-energize and isolate any equipment before performing fastener service on live mechanical or electrical assemblies. Distorted-thread lock nuts are single-use by most engineering standards — replace with a new nut if removed from service. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being fastened.
