Bowmalloy BOW36357 Hex Head Cap Screw 3/8-24 Grade 9

Product Description

The BOWMALLOY BOW36357 is a Grade 9 steel hex head cap screw designed for high-strength fastening applications in trade and industrial settings. Measuring 3/8-24 thread size with a 1-3/4 inch length under head, this partially threaded fastener features BOWMALLOY's Bowma-Guard zinc-plated clear chromate finish for corrosion resistance. It is suited for mechanical assemblies, structural connections, and equipment installations where high clamping force and fastener integrity are critical. Licensed tradespeople and maintenance professionals working in HVAC, plumbing, electrical, and general mechanical service rely on Grade 9 fasteners for demanding load conditions.

This hex head cap screw is appropriate for use in both residential and commercial mechanical assemblies where UNF fine-thread engagement and partial threading are specified. The 3/8-24 fine-thread profile provides superior thread engagement and vibration resistance compared to coarse-thread equivalents, making it a common choice in precision equipment installations, motor mounts, and bracket assemblies across multiple trades.

Key Features

• Grade 9 steel construction delivers high tensile strength for demanding fastener applications
• Partial threading allows for precise clamping and grip-length control in bolted joints
• 3/8-24 UNF fine-thread profile provides strong thread engagement and vibration resistance
• Bowma-Guard zinc-plated clear chromate finish offers corrosion protection for extended service life
• Inch measurement system with 1-3/4 inch length under head for standard tooling compatibility

Compatibility

Designed as a standard inch-series hex head cap screw suitable for use in mechanical assemblies, equipment frames, and structural connections requiring a 3/8-24 UNF partially threaded fastener in Grade 9 steel.

Installation Notes

Installation is appropriate for qualified mechanics and trade professionals working on mechanical or structural assemblies. Always de-energize or shut off any equipment before fastener replacement or assembly work. Use a properly sized hex socket or open-end wrench rated for the fastener grade to avoid rounding the head. Follow applicable industry standards and equipment manufacturer specifications for torque and joint design.
