Bowmalloy BOWMP36173 Hex Head Cap Screw 3/4-10 2-1/4 in

Product Description

The BOWMALLOY BOWMP36173 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 9 steel, this fastener delivers tensile strength above standard Grade 5 and Grade 8 hardware, making it well suited for demanding load-bearing connections. The 3/4-10 thread size and 2-1/4 inch length under head provide a reliable grip range for heavy-duty bolted joints. A proprietary Bowma-Guard finish is applied to enhance corrosion resistance in exposed or moderately harsh service environments. Licensed trades and industrial maintenance technicians are the primary installers of this fastener class.

This cap screw is used across a wide range of industrial and mechanical installations where superior clamping force and vibration resistance are required. Typical applications include heavy equipment assembly, structural steel connections, hydraulic component mounting, and machinery maintenance. The fully threaded shank maximizes thread engagement across the full fastener length, making it appropriate for through-bolt and tapped-hole configurations in both original equipment and field-repair scenarios.

Key Features

• Grade 9 steel construction for high tensile strength beyond standard Grade 8 fasteners
• Fully threaded shank for maximum thread engagement in through-bolt and tapped-hole applications
• 3/4-10 UNC thread size for broad compatibility with standard inch-series hardware
• 2-1/4 inch length under head suits medium-depth clamping and structural connections
• Bowma-Guard finish provides enhanced corrosion resistance over plain steel
• Inch measurement system for direct use with standard SAE tooling

Compatibility

Designed for use in standard 3/4-10 UNC tapped holes and through-bolt assemblies requiring Grade 9 fastener strength ratings in inch-series mechanical and structural applications.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with high-strength fastener torque requirements for the specific joint and material stack. Always verify thread engagement depth and hole condition before installation. Use calibrated torque tooling appropriate for 3/4-inch Grade 9 fasteners and follow applicable industry or equipment manufacturer specifications. Do not mix Grade 9 hardware with lower-grade nuts or plates that may not support the fastener's rated load.
