Bowmalloy BOWMP36603 Hex Nut 3/8-16 Grade 9 Steel

Product Description

The BOWMALLOY BOWMP36603 is a Grade 9 steel hex nut with a 3/8-16 thread size and a Bowma-Guard protective finish. Grade 9 fasteners meet high-strength requirements, making this nut suited for demanding mechanical and structural applications where a standard Grade 5 or Grade 8 nut would be undersized for the load. The Bowma-Guard finish provides corrosion resistance without sacrificing the clamping performance expected from a high-grade fastener. With a width across flats of 0.5625 inches and a height of 0.330 inches, the nut accepts a standard 9/16-inch wrench. Sold in a package of 50.

This hex nut is used in industrial, construction, and mechanical assembly applications where high-strength fastening is required. It is appropriate for use with Grade 9 bolts and threaded rod in both original equipment manufacturing and field repair scenarios. Right-hand thread direction follows standard convention, making it compatible with the vast majority of 3/8-16 threaded fastener applications. Typical installers include millwrights, pipefitters, electricians, and general contractors working on structural connections or equipment mounting.

Installation Notes

Installation is performed by any trade working with structural or mechanical fastener assemblies. Always match the nut grade to the bolt or threaded rod grade to maintain rated joint strength. Torque to the value specified in the applicable engineering or equipment specification for the assembly. Inspect threads for damage or contamination before installation to ensure proper engagement and clamp load.
