Value Collection 250071 Coupling Nut 3/8-16 Unc Steel

Product Description

The VALUE COLLECTION 250071 is a standard coupling nut used to join two externally threaded fasteners along a common axis. Made from steel with a zinc-plated finish, this nut features a 3/8-16 UNC right-hand thread and measures 1-3/4 inches overall length with a 5/8-inch width across flats. Coupling nuts are a routine hardware component for threaded rod extensions, turnbuckle assemblies, and structural fastening applications across mechanical, electrical, and construction trades. The zinc plating provides a basic level of corrosion resistance suitable for general indoor and sheltered environments.

This coupling nut is suited for light to medium fastening tasks where a standard Grade 2 steel fastener meets load requirements. Typical applications include extending all-thread rod in electrical conduit support systems, mechanical framing assemblies, HVAC equipment mounting, plumbing support structures, and general construction. The 3/8-16 UNC thread is one of the most common inch-series thread sizes found in trade work, making this nut widely applicable across multiple disciplines.

Key Features

• 3/8-16 UNC right-hand thread for compatibility with standard inch-series threaded rod and fasteners
• 1-3/4 inch overall length provides substantial thread engagement on both mating fasteners
• 5/8 inch width across flats fits standard hex wrench and socket tooling
• Zinc-plated steel finish offers basic corrosion resistance for general-purpose use
• Grade 2 material grade suitable for light to medium load applications

Compatibility

Designed for use with 3/8-16 UNC externally threaded fasteners including all-thread rod, bolts, and studs following the Unified National Coarse thread standard.

Installation Notes

Installation requires a standard hex wrench or socket sized to 5/8 inch. Ensure mating fasteners are clean and free of thread damage before engagement. Apply appropriate thread engagement depth on both ends of the nut per applicable mechanical or structural guidelines. Follow OSHA and applicable building or mechanical codes when using coupling nuts in structural or load-bearing assemblies.
