Bowmalloy BOWMP36054 Hex Head Cap Screw 3/8-16x1 Grade 9

Product Description

The BOWMALLOY BOWMP36054 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial and construction environments. Manufactured from Grade 9 steel, this fastener exceeds the tensile strength requirements of standard Grade 5 and Grade 8 fasteners, making it well suited for demanding structural and mechanical assemblies. The Bowma-Guard finish provides a protective coating that helps resist corrosion in service environments where exposure to moisture or mild chemicals is a concern. Installed using standard hex drive tooling, this screw is sized at 3/8-16 thread with a 1 inch length under head and is fully threaded from tip to head.

This cap screw is used in a wide range of industrial, mechanical, and structural assemblies where high-strength inch-series fasteners are required. Typical applications include equipment mounting, machinery assembly, structural steel connections, and heavy fabrication work. The 3/8-16 unified coarse thread pattern is among the most common inch-series thread standards, making this screw compatible with a broad set of nuts, inserts, and tapped hole configurations found across manufacturing and maintenance trades. Sold in quantities of 25 per package.

Key Features

• Grade 9 steel construction exceeds Grade 8 tensile and proof load requirements
• Fully threaded from head to tip for maximum thread engagement across the full grip length
• Bowma-Guard finish provides corrosion-resistant protective coating
• 3/8-16 unified coarse thread - widely used inch-series standard
• 1 inch length under head suits shallow to medium-depth fastening applications
• Sold in 25-piece packages to support job-quantity purchasing

Compatibility

Designed for use with standard 3/8-16 inch-series hex nuts, flat washers, lock washers, and tapped holes conforming to ASME/ANSI unified coarse thread specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque requirements for Grade 9 hardware. Always consult the applicable engineering specification or torque chart for the correct clamp load based on joint material and lubrication condition. Power down or de-energize any equipment before fastening or replacing hardware in electrical or mechanical enclosures. Do not mix inch-series and metric fasteners in the same assembly.
