Value Collection CLNI20500-025B Hex Lock Nut 1/2-13

Product Description

The VALUE COLLECTION CLNI20500-025B is a distorted-thread hex lock nut used to secure fastener assemblies where vibration resistance is required. The locking function is achieved through a deformed thread profile that creates interference with the mating bolt thread, eliminating the need for secondary locking devices such as washers or adhesives. Sized at 1/2-13 UNC/UNF thread, this nut measures 7/16 inches high with a 3/4-inch width across flats. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in light-duty indoor and sheltered environments. This fastener is installed by maintenance technicians, millwrights, and general tradespeople.

This hex lock nut is suited for general-purpose mechanical assemblies, equipment mounting, and structural fastening applications where a reusable locking nut is preferred. The distorted-thread design functions as a two-way lock nut, providing resistance to both tightening and loosening torque. Typical applications include light fabrication, HVAC equipment mounting, panel assembly, and general industrial maintenance. Minimum order quantity is 25 pieces per order.

Key Features

• Distorted-thread locking style provides vibration-resistant clamping without secondary hardware
• Two-way lock nut design resists both clockwise and counterclockwise loosening
• 1/2-13 thread size compatible with UNC and UNF fastener standards
• Grade 2 steel construction for light-to-medium duty fastening applications
• Zinc-plated finish for basic corrosion protection in sheltered environments
• Right-hand thread direction for standard installation with conventional tooling

Compatibility

Designed as a general-purpose replacement hex lock nut for 1/2-13 UNC and UNF threaded bolt assemblies in light-duty mechanical and industrial applications.

Installation Notes

Installation requires a standard 3/4-inch hex wrench or socket. Power down or de-energize any associated equipment before servicing fastener assemblies. The distorted-thread profile may increase installation torque compared to standard hex nuts; do not force the nut onto a damaged or mismatched thread. Reuse should be evaluated on a per-application basis, as repeated cycling can reduce the locking effectiveness of distorted-thread fasteners.
