Bowmalloy BOWMP36062 Hex Head Cap Screw 3/8-16x3 Grade 9

Product Description

The BOWMALLOY BOWMP36062 is a Grade 9 steel hex head cap screw in a 3/8-16 thread size with a 3-inch length under the head. It features partial threading and a Bowma-Guard protective finish. This fastener is suited for heavy-duty mechanical and structural assemblies where high-strength fasteners are required. Licensed tradespeople, maintenance mechanics, and industrial assemblers working within inch-standard fastener specifications will find this screw appropriate for demanding load-bearing and bolted-joint applications.

This cap screw is used in industrial, commercial, and trade applications requiring a high-strength inch-series fastener. Typical install scenarios include equipment mounting, structural steel connections, machinery frames, and other assemblies where Grade 9 tensile strength and corrosion-resistant Bowma-Guard coating are specified. It is sold in packages of 10 units with a minimum order quantity of 1 package, making it practical for both service calls and larger maintenance jobs.

Key Features

• Grade 9 steel construction provides elevated proof load and tensile strength versus Grade 5 or Grade 8 fasteners
• Bowma-Guard finish offers corrosion protection for extended service life in demanding environments
• Partial threading allows for precise grip-length control in bolted joints
• 3/8-16 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• 3-inch length under head suits applications requiring deeper thread engagement or thicker material stacks
• Packaged in quantities of 10 for efficient inventory and job-site use

Compatibility

Designed for use with standard 3/8-16 UNC inch-series nuts, washers, and tapped holes in Grade 9 or higher rated assemblies across industrial and commercial mechanical applications.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with high-strength fastener procedures. Always verify that the mating nut, tapped hole, and structural member are rated for Grade 9 fastener loads before assembly. Use a calibrated torque wrench and follow the applicable torque specifications from the equipment manufacturer or relevant ASME or ASTM standards. Inspect threads for damage before installation and do not reuse fasteners that show signs of deformation or corrosion.
