Value Collection CLNI21000-025BX Hex Lock Nut 1-8 Grade 2

Product Description

The VALUE COLLECTION CLNI21000-025BX is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loading. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in dry to mildly humid environments. The nut features a 1-8 UNC thread size, a right-hand thread direction, and measures 55/64 inches in height with a 1-1/2 inch width across flats. This is a two-way lock nut, meaning it can be driven on or off without losing its locking function. Sold in a minimum order quantity of 25 units, it is suited for general mechanical assembly, maintenance, and repair work across a range of trades.

This nut is used in structural, mechanical, and equipment fastening applications where vibration or movement could cause standard nuts to back off. It fits 1-8 UNC and UNF threaded fasteners and is appropriate for residential and light commercial maintenance contexts, including HVAC equipment panels, plumbing support hardware, electrical enclosure mounting, and general fabrication. Licensed tradespeople and maintenance technicians installing or servicing equipment with inch-series hardware will find this a standard shop-stock item.

Key Features

• Distorted-thread locking style prevents self-loosening without a separate locking insert or adhesive
• Two-way lock nut design allows installation and removal while retaining locking capability
• Grade 2 steel construction suitable for general-purpose fastening loads
• Zinc-plated finish adds baseline corrosion resistance for indoor and sheltered outdoor use
• Right-hand thread direction compatible with standard UNC and UNF inch-series fasteners
• Sold in multiples of 25 units, practical for shop stock and recurring maintenance use

Compatibility

Designed for use with 1-8 UNC and UNF inch-series threaded fasteners in general mechanical, HVAC, plumbing, and electrical assembly applications requiring a distorted-thread locking hex nut.

Installation Notes

Installation and removal require a standard 1-1/2 inch hex wrench or socket. Shut down and de-energize any equipment before servicing fastened assemblies. Do not exceed the load ratings appropriate for Grade 2 steel hardware, and avoid use in high-temperature or chemically aggressive environments where the zinc finish may degrade. Always verify thread engagement depth is sufficient for the applied load per applicable mechanical codes.
