Bowmalloy BOW36330 Hex Head Cap Screw 5/16-24 Grade 9

Product Description

The BOWMALLOY BOW36330 is a Grade 9 alloy steel hex head cap screw designed for high-strength fastening applications where standard Grade 5 or Grade 8 hardware is insufficient. This screw measures 5/16-24 (fine thread) with a 1-1/4 inch length under head and is fully threaded from tip to bearing surface. The Bowma-Guard zinc-plated clear chromate finish provides corrosion resistance suitable for general industrial, mechanical, and structural assembly. Licensed tradespeople and maintenance technicians working in demanding environments will find this fastener appropriate for high-load, vibration-prone joints.

This hex head cap screw is used in industrial machinery assembly, heavy equipment maintenance, automotive applications, and structural mechanical assemblies where a fine-thread 5/16-24 pattern is specified. The fully threaded shank maximizes thread engagement across the full clamped length, making it well suited for applications requiring precise torque control and strong clamping force. Sold in a package quantity of 100 with a minimum order quantity of 1 package.

Key Features

• Grade 9 alloy steel construction exceeds the strength of standard Grade 8 fasteners
• 5/16-24 fine thread for increased tensile strength and finer torque adjustment
• Fully threaded shank for maximum thread engagement in short-clamp applications
• Bowma-Guard zinc-plated clear chromate finish for corrosion resistance
• Inch measurement system, compatible with standard SAE tooling
• Packaged in quantities of 100 per bag for job-site and shop use

Compatibility

Designed for use in any application requiring a 5/16-24 fine-thread hex head cap screw with a 1-1/4 inch length under head, following standard inch-series fastener specifications.

Installation Notes

Installation requires a standard SAE hex wrench or socket sized for a 5/16-24 hex head cap screw. Always verify the mating thread is clean and undamaged before installation. Follow the torque specifications provided by the equipment manufacturer or applicable mechanical code for Grade 9 fasteners. De-energize or shut down any equipment before performing fastener replacement or assembly work on live systems.
