Bowmalloy BOW36360 Hex Head Cap Screw 3/8-24 Grade 9

Product Description

The BOWMALLOY BOW36360 is a Grade 9 steel hex head cap screw designed for high-strength fastening applications in demanding mechanical and structural assemblies. Measuring 3/8-24 thread pitch with a 2.5-inch length under head, this screw features partial threading and a Bowma-Guard zinc-plated clear chromate finish that provides corrosion resistance. Grade 9 fasteners exceed the tensile strength of common Grade 5 and Grade 8 hardware, making them a go-to choice where heavy-duty clamping load is required. These screws are sold in packages of 50 and are suitable for use by mechanics, millwrights, and maintenance technicians working with inch-measurement fastener systems.

The BOW36360 is suited for industrial, agricultural, and heavy equipment applications where fine-thread 3/8-24 fasteners are specified. The fine thread pitch improves thread engagement strength and torque retention compared to coarse-thread equivalents, making it appropriate for metal-to-metal joints subject to vibration or dynamic loading. Partially threaded shanks provide a cleaner grip zone for applications requiring a shoulder or clamping section free of threads.

Key Features

• Grade 9 steel construction for high tensile strength exceeding Grade 8 specifications
• 3/8-24 fine-thread pitch for improved thread engagement and vibration resistance
• Partially threaded shank provides a smooth grip zone for precision clamping
• Bowma-Guard zinc-plated clear chromate finish for corrosion protection
• Inch measurement system; UNSPSC Code 31161501
• Packaged in quantities of 50 for shop and field use

Compatibility

Designed for use in any application specifying a 3/8-24 fine-thread hex head cap screw with a 2.5-inch length under head in the inch measurement system.

Installation Notes

Installation should be performed by qualified mechanics or maintenance technicians familiar with high-strength fastener procedures. Always confirm mating thread condition and clean threads before installation. Torque to the value specified in the equipment service manual or engineering drawing for Grade 9 fasteners of this diameter and pitch. Do not substitute Grade 9 fasteners in joints designed for lower-grade hardware without engineering approval.
