Value Collection 320375BR Heavy Hex Nut 1-1/2-6 Unc

Product Description

The VALUE COLLECTION 320375BR is a heavy hex nut threaded to a 1-1/2-6 UNC specification in Grade 2 steel with a zinc-plated finish. Heavy hex nuts feature a wider, thicker profile than standard hex nuts, providing greater bearing surface and improved resistance to loosening under load. The zinc plating delivers basic corrosion resistance suitable for general indoor and sheltered outdoor applications. This fastener is used by pipefitters, millwrights, ironworkers, and general contractors wherever a 1-1/2-6 UNC heavy hex nut is required per assembly or project specifications.

This heavy hex nut is suited for structural connections, pipe flange assemblies, heavy equipment mounting, and general industrial fastening where a larger bearing surface is specified. The right-hand thread direction conforms to standard UNC fastener practice. With a width across flats of 2.375 inches and a height of 1.4688 inches, it is sized for use with 1-1/2-inch diameter UNC bolts and threaded rod commonly found in commercial and industrial construction and mechanical systems.

Key Features

• Heavy hex profile provides wider bearing surface compared to standard hex nuts
• Grade 2 steel construction meets general-purpose structural fastener requirements
• Zinc-plated finish provides basic corrosion protection for indoor and sheltered installations
• Right-hand UNC thread direction for compatibility with standard UNC threaded fasteners
• Width across flats of 2.375 inches suits standard 1-1/2-inch heavy hex wrench sizes

Compatibility

Designed for use with 1-1/2-6 UNC threaded bolts and threaded rod in general industrial and construction fastening applications.

Installation Notes

Installation is performed by pipefitters, ironworkers, millwrights, or general tradespeople using a standard heavy hex wrench or impact socket sized for a 2.375-inch across-flats dimension. Ensure the mating bolt or threaded rod is also 1-1/2-6 UNC and that threads are clean and free of debris before assembly. Do not mix with metric or fine-thread fasteners. Torque to project-specified values per applicable structural or mechanical standards.
