Bowmalloy BOWMP36150 Hex Head Cap Screw 5/8-11 Grade 9

Product Description

The BOWMALLOY BOWMP36150 is a Grade 9 steel hex head cap screw designed for high-strength bolted connections in demanding industrial and mechanical applications. It features a 5/8-11 thread size, a 2-1/4 inch length under head, and partial threading. The Bowma-Guard finish provides corrosion resistance suited to harsh service environments. This fastener is installed by millwrights, maintenance mechanics, and heavy-equipment technicians who require a reliable, high-tensile fastener in structural and mechanical assemblies.

This screw is a standard inch-series hex head cap screw used in industrial machinery, agricultural equipment, construction equipment, and structural steel applications where Grade 9 tensile strength is specified. The partial threading allows for precise clamping force and proper seating in thick or stacked material joints. It is appropriate for both indoor and outdoor installations where corrosion protection is required.

Key Features

• Grade 9 steel construction provides high tensile strength for demanding load-bearing connections
• Bowma-Guard finish delivers corrosion resistance in outdoor and harsh-environment installations
• 5/8-11 UNC thread size suits standard American inch-series hardware specifications
• Partially threaded shank allows precise clamping with proper grip length in thick assemblies
• 2-1/4 inch length under head accommodates medium-depth fastening applications

Compatibility

Designed for use with standard 5/8-11 UNC inch-series nuts and tapped holes in Grade 9 or compatible high-strength bolted joint applications.

Installation Notes

Installation should be performed by qualified mechanics or millwrights following applicable torque specifications from engineering references or equipment manufacturer documentation. Always verify hole size and thread engagement before driving. Proper torque wrenches should be used to achieve specified clamp load without fastener damage. De-energize or lock out any equipment before performing fastener work on live machinery.
