Bowmalloy BOWMP36602 Hex Nut 5/16-18 Grade 9 Steel

Product Description

The BOWMALLOY BOWMP36602 is a Grade 9 steel hex nut with a 5/16-18 UNC thread size and a Bowma-Guard protective finish. Grade 9 fasteners are rated for high-strength structural and mechanical applications where standard Grade 5 or Grade 8 hardware is not sufficient. The Bowma-Guard finish provides corrosion resistance for use in demanding environments. This nut measures 0.5 inches across the flats and 0.268 inches in height, conforming to standard hex nut geometry for 5/16-18 thread engagement. Sold in packages of 50, it is suited for contractors, millwrights, OEM assemblers, and maintenance professionals who require consistent, high-grade fastener stock.

This hex nut is appropriate for heavy-duty mechanical assemblies, structural connections, and industrial equipment maintenance where high-tensile fasteners are specified. The right-hand thread direction is standard for the vast majority of bolted connections across HVAC equipment frames, electrical enclosures, plumbing support brackets, and general mechanical structures. The 5/16-18 thread size is one of the most common coarse-thread fastener sizes used in North American trade work, making this nut a reliable stocking item for service vans, job sites, and shop inventory.

Installation Notes

Installation is performed by mechanics, millwrights, or trade technicians using a standard 1/2-inch wrench or socket.

Verify thread engagement depth meets the requirements of the applicable design specification before torquing to final value.
