Value Collection MSC-72047509 5/8-11 Unc Heavy Hex Nut

Product Description

The VALUE COLLECTION MSC-72047509 is a heavy hex nut threaded to the 5/8-11 UNC standard, designed for high-load fastening applications in structural, mechanical, and industrial assemblies. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this nut provides corrosion resistance suited to outdoor, wet, or exposed environments. It measures 1-1/16 inches across the flats and 39/64 inches in height, following the heavy hex profile that provides greater bearing surface and wall thickness than standard hex nuts. Right-hand thread direction is standard for conventional assembly. Tradespeople in construction, infrastructure, and industrial maintenance rely on this fastener where structural load or harsh conditions demand a heavier-duty nut profile.

This heavy hex nut is appropriate for use in structural steel connections, utility and electrical transmission hardware, anchor bolt assemblies, and general industrial bolted joints. The hot-dipped galvanized coating makes it a practical choice for outdoor installations, bridge work, utility structures, and any application where bare steel would be subject to moisture or chemical exposure. Minimum order quantity is 25 pieces.

Key Features

• Heavy hex profile provides greater bearing surface and wall thickness compared to standard hex nuts
• Hot-dipped galvanized finish delivers corrosion resistance for outdoor and exposed environments
• 5/8-11 UNC right-hand thread for compatibility with standard inch-series threaded rod and bolts
• Grade 2 steel construction suited for general structural and mechanical fastening
• 1-1/16 inch across-flats width conforms to heavy hex dimensional standards

Compatibility

Designed for use with 5/8-11 UNC threaded bolts, rods, and studs requiring a heavy hex nut profile in structural or industrial fastening applications.

Installation Notes

Installation is typically performed by ironworkers, millwrights, electricians, or general construction tradespeople using standard hex wrenches or impact tools sized for 1-1/16 inch across flats. Torque requirements should be determined by the engineer of record or applicable structural specifications for the assembly. Do not mix galvanized and non-galvanized hardware in the same joint without consulting applicable standards. Follow AISC, ASTM, or project-specific fastener installation procedures as required.
