Value Collection CPLGI20620-025BX Coupling Nut 5/8-11 Unc

Product Description

The VALUE COLLECTION CPLGI20620-025BX is a standard coupling nut used to join or extend two externally threaded fasteners along a common axis. Machined from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this nut carries a 5/8-11 UNC thread specification with right-hand thread direction. The overall length is 2.125 inches and the width across flats measures 13/16 inches. It is installed with a standard open-end or box wrench and suits general mechanical assembly, threaded rod extension, and structural fastening work across trade applications including HVAC equipment mounting, plumbing support systems, and general construction.

This coupling nut is suited for use in light-to-medium duty fastening applications where threaded rod or bolt extension is required. Typical installations include suspended pipe hangers, equipment support rods, and structural tie-rod assemblies. The 5/8-11 UNC thread form is a widely used coarse-thread standard in inch-based mechanical assemblies, making this nut compatible with standard UNC threaded rod and bolts of matching diameter and pitch. It is appropriate for indoor and protected outdoor environments where zinc plating provides adequate surface protection.

Key Features

• 5/8-11 UNC right-hand thread for broad compatibility with standard inch-series threaded fasteners
• Grade 2 steel construction provides adequate strength for general-duty fastening applications
• Zinc-plated finish offers basic corrosion resistance in dry or protected environments
• 2.125-inch overall length allows full thread engagement when joining or extending threaded rod
• 13/16-inch width across flats fits standard SAE open-end and box wrenches

Compatibility

Designed for use with 5/8-11 UNC threaded rod and bolts conforming to inch-series coarse-thread standards. Suitable as a general-duty coupling nut in standard mechanical and structural fastening assemblies.

Installation Notes

Installation is performed with a standard open-end or box wrench sized to 13/16 inches across flats. De-energize and isolate any equipment or structure before beginning fastener work in electrical or mechanical systems. Ensure both mating threaded components are clean, undamaged, and of matching UNC thread specification before assembly. Do not exceed the load rating appropriate for Grade 2 steel fasteners in structural or load-bearing applications.
