Bowmalloy BOWMP36355 Hex Head Cap Screw 3/8-24 Grade 9

Product Description

The BOWMALLOY BOWMP36355 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It is manufactured from Grade 9 steel with a Bowma-Guard finish applied for corrosion resistance. The fastener measures 3/8-24 thread size with a 1-1/4 inch length under head and is fully threaded along its entire shank length. This screw is selected by millwrights, maintenance technicians, and mechanical contractors who require a reliable, high-grade fastener for demanding service environments.

This cap screw is suited for use in heavy equipment, industrial machinery, agricultural equipment, and structural assemblies where Grade 9 tensile strength is specified. The 3/8-24 fine thread pitch provides greater thread engagement and improved resistance to vibration loosening compared to coarse thread equivalents, making it a preferred choice for dynamic or high-vibration installations.

Key Features

• Grade 9 steel construction for high-strength fastening performance
• Fully threaded shank for maximum engagement along the full 1-1/4 inch length
• 3/8-24 fine thread pitch resists loosening under vibration
• Bowma-Guard finish provides corrosion protection in service environments
• Inch measurement system; UNSPSC Code 31161501

Compatibility

Designed as an OEM-style replacement or service fastener for industrial and mechanical assemblies requiring a 3/8-24 fine thread, Grade 9 hex head cap screw with fully threaded shank.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using an appropriate hex socket or wrench sized for the hex head. Always verify thread class and mating thread condition before installation. Consult the equipment manufacturer torque specifications for Grade 9 fasteners at this thread size before final tightening. Inspect the Bowma-Guard finish for damage before installation in corrosive environments and replace any fastener that shows pre-installation coating compromise.
