Bowmalloy BOWMP36335 Hex Head Cap Screw 5/16-24 2-1/2 in

Product Description

The BOWMALLOY BOWMP36335 is a Grade 9 steel hex head cap screw sized 5/16-24 with a 2.5-inch length under head. It features partial threading and a Bowma-Guard protective finish. Grade 9 fasteners deliver high tensile strength suited to demanding mechanical and structural applications. The Bowma-Guard finish provides corrosion resistance in environments where standard zinc plating falls short. This screw is installed by millwrights, maintenance mechanics, and heavy-equipment technicians who require a reliable, high-strength inch-series fastener in fine-thread configurations.

This cap screw is used in industrial machinery, heavy equipment assemblies, and structural fabrication where fine-thread engagement and elevated clamp load are required. The 5/16-24 fine-thread pitch offers improved tensile strength and better resistance to vibration loosening compared to coarse-thread equivalents. Typical install scenarios include equipment mounting flanges, power transmission components, and precision mechanical assemblies where controlled torque and joint integrity are critical.

Key Features

• Grade 9 steel construction for high tensile and proof-load strength
• 5/16-24 fine-thread series for superior vibration resistance and tighter thread engagement
• 2.5-inch length under head with partial threading for shank-bearing load applications
• Bowma-Guard finish provides enhanced corrosion protection over standard plating
• Hex head drive for use with standard hex wrenches and socket sets
• Inch measurement system, UNSPSC Code 31161501

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications requiring a 5/16-24 fine-thread, Grade 9 hex head cap screw with a 2.5-inch length under head and partial threading.

Installation Notes

Installation should be performed by qualified mechanics or technicians familiar with inch-series fastener standards. Always degrease mating threads and inspect tapped holes for damage before installation. Torque to the value specified by the equipment manufacturer for Grade 9 fasteners of this diameter and thread pitch. Follow applicable industry standards such as ASME B18.2.1 for hex head cap screw installation practices.
