Bowmalloy BOWMP36064 Hex Head Cap Screw 3/8-16 X 3.5 in

Product Description

The BOWMALLOY BOWMP36064 is a Grade 9 steel hex head cap screw with a 3/8-16 thread size and a 3.5-inch length under the head. It features a Bowma-Guard finish for corrosion resistance and is partially threaded along the shank. This fastener is designed for high-strength bolted connections in demanding mechanical and structural assemblies. It is typically installed by millwrights, maintenance technicians, and industrial mechanics who require reliable clamping force in critical joint applications.

This hex head cap screw suits industrial, commercial, and heavy equipment applications where Grade 9 high-strength fasteners are specified. The partial threading allows for a smooth shank section that handles shear loads effectively, making it appropriate for machinery frames, mounting plates, structural brackets, and similar bolted assemblies requiring both tensile and shear performance.

Key Features

• Grade 9 steel construction for high tensile and proof load strength
• 3/8-16 unified coarse thread (UNC) for broad tooling compatibility
• 3.5-inch length under head suits thicker stack-up assemblies
• Partially threaded shank provides a bearing surface for shear load resistance
• Bowma-Guard finish for added corrosion protection in tough environments

Compatibility

Designed as an OEM-style replacement or standard-fitment fastener for bolted assemblies requiring a 3/8-16 UNC hex head cap screw with a 3.5-inch grip length and Grade 9 minimum strength rating.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician following applicable industry standards and equipment manufacturer torque specifications. Always ensure the mating threads and bearing surfaces are clean and free of debris before assembly. Use a properly calibrated torque wrench sized for 3/8-inch fasteners, and consult the joint design specification for required clamp load. Follow lockout/tagout procedures and de-energize all associated equipment before performing any fastener work on live machinery.
