Bowmalloy BOWMP36615 Hex Nut 1/2-20 Grade 9 Steel

Product Description

The BOWMALLOY BOWMP36615 is a Grade 9 steel hex nut with a 1/2-20 thread size and a Bowma-Guard protective finish. Grade 9 hardware meets high-strength fastener standards, making this nut suitable for demanding mechanical and structural connections where standard Grade 5 or Grade 8 hardware may not be sufficient. The right-hand thread pattern is the industry-standard orientation. Width across flats measures 0.75 inches, and the nut height is 0.44 inches. Sold in packs of 25, this nut is a reliable choice for contractors, mechanics, and tradespeople working on high-load assemblies.

This hex nut is appropriate for use in industrial, mechanical, and trade applications requiring a fine-thread 1/2-20 fastener with elevated tensile strength. The Bowma-Guard finish provides corrosion resistance, making it suitable for environments where standard uncoated steel hardware may be vulnerable to oxidation. Typical applications include structural bolted connections, heavy equipment repair, and assemblies governed by torque and load specifications that demand Grade 9 rated fasteners.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener procedures. Always ensure the mating bolt or stud carries an equivalent or higher grade rating before applying final torque. Clean threads prior to installation to avoid false torque readings. Follow applicable ASME or equipment manufacturer torque specifications for Grade 9 fasteners in the specific application.
