Value Collection CLNI20620-025B Hex Lock Nut 5/8-11 25 Pack

Product Description

The VALUE COLLECTION CLNI20620-025B is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads. Sized at 5/8-11 UNC/UNF thread, it measures 35/64 inches high with a 15/16-inch width across flats and features a right-hand thread direction. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this nut suits general-purpose mechanical and structural fastening applications. It ships in a minimum order quantity of 25 pieces, making it practical for batch installation jobs or maintenance stock replenishment.

This nut is appropriate for residential and light commercial mechanical assemblies where a two-way locking action is needed without the use of a separate locking insert or adhesive. The distorted-thread locking style creates interference with the mating bolt threads, providing a re-usable lock that does not rely on a nylon element. Typical applications include equipment mounting, structural frameworks, HVAC equipment bases, and general mechanical fastening where UNC or UNF thread engagement is specified.

Key Features

• Distorted-thread locking style resists loosening from vibration without a separate insert
• 5/8-11 thread size compatible with UNC and UNF fastener standards
• Grade 2 steel construction for general-purpose strength requirements
• Zinc-plated finish provides basic corrosion protection in dry or mildly humid environments
• Right-hand thread direction for standard installation with conventional tools
• Sold in multiples of 25 for efficient stocking and batch installations

Compatibility

Designed as a general-purpose replacement or stocking nut for 5/8-11 UNC and UNF threaded fastener applications meeting Grade 2 steel requirements.

Installation Notes

Install using a standard 15/16-inch wrench or socket; de-energize and lock out any equipment before servicing fastened assemblies under load. Distorted-thread lock nuts may require slightly higher installation torque than standard hex nuts due to thread interference. Do not exceed the rated mechanical load for Grade 2 steel. These nuts are intended for right-hand threaded bolts only.
