Bowmalloy BOWMP36453 Hex Head Cap Screw 5/8-18 X 3 in

Product Description

The BOWMALLOY BOWMP36453 is a Grade 9 steel hex head cap screw designed for high-strength fastening applications. It features a 5/8-18 UNF thread size, a 3-inch length under head, and partial threading along the shank. The Bowma-Guard finish provides corrosion resistance for use in demanding environments. This fastener is installed by maintenance technicians, millwrights, industrial mechanics, and contractors working on heavy equipment, structural assemblies, and mechanical systems requiring a fine-thread, high-tensile fastener.

This cap screw is suited for industrial, commercial, and construction applications where a fine-pitch thread and Grade 9 tensile strength are specified. The partial threading allows the unthreaded shank to bear shear loads while the threaded portion provides secure clamping. Typical installations include heavy machinery, structural steel connections, and equipment frames where vibration resistance and joint integrity are priorities.

Key Features

• Grade 9 steel construction delivers high tensile and proof load strength
• 5/8-18 UNF fine thread for precise torque control and resistance to loosening
• 3-inch length under head accommodates thick material stacks
• Partially threaded shank supports shear load applications
• Bowma-Guard finish provides corrosion protection in harsh service environments
• Inch measurement system compatible with standard SAE tooling

Compatibility

Designed as a direct-fit Grade 9 hex head cap screw for applications specifying a 5/8-18 UNF x 3-inch partially threaded fastener in inch-measurement systems.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople following applicable fastener torque specifications for Grade 9 hardware. Always verify hole thread condition and fastener engagement before final tightening. Use calibrated torque equipment to achieve proper clamp load without overloading the joint. Inspect the Bowma-Guard finish for damage before installation to ensure corrosion protection integrity.
