Value Collection R88412844 Hex Cap Screw 3/8-16 X 2-3/4 in 316 Ss

Product Description

The VALUE COLLECTION R88412844 is a 3/8-16 UNC hex head cap screw measuring 2-3/4 inches under the head, manufactured from Grade 316 stainless steel with an uncoated finish. It features partial threading along the shank, which provides a smooth bearing surface between joined materials and reduces stress concentration at the thread runout. Grade 316 stainless steel offers superior corrosion resistance compared to Grade 304, making it a preferred fastener choice in marine, chemical processing, food service, and outdoor structural applications where exposure to moisture, salt, or mild acids is a regular service condition. Machinists, maintenance mechanics, pipefitters, and general contractors typically specify and install this fastener type.

This hex head cap screw is suited for general structural and mechanical assembly work requiring a corrosion-resistant fastener in inch-series thread sizes. Its 3/8-16 UNC thread form is a coarse-thread standard widely used in fabricated steel assemblies, pipe supports, equipment frames, and enclosure hardware. The partially threaded shank is appropriate for through-bolt applications where clamping force and shear load must be distributed along an unthreaded grip length. It is commonly installed in both light commercial and industrial maintenance environments.

Key Features

• Grade 316 stainless steel construction for strong resistance to corrosion, oxidation, and chloride exposure
• 3/8-16 UNC coarse thread standard for broad compatibility with standard inch-series nuts and tapped holes
• Partial threading provides a smooth grip section for shear-load applications and cleaner clamping
• Uncoated finish — no plating or coating that could affect dimensional tolerances or galvanic compatibility
• Hex head drive style accepts standard hex wrenches and sockets for high-torque installation
• Length under head is 2-3/4 inches, measured per standard fastener length convention

Compatibility

Designed as a standard inch-series hex head cap screw for use with any 3/8-16 UNC tapped hole, hex nut, or coupling nut in applications requiring Grade 316 stainless steel fasteners.

Installation Notes

Install using a standard hex wrench or socket sized for a 3/8-inch hex head cap screw. Ensure mating threads are clean and free of debris before assembly. When installing stainless steel fasteners into stainless or aluminum tapped holes, apply an anti-seize compound to the threads to prevent galling. Torque to values specified by the assembly engineer or applicable structural standard — do not estimate torque on structural or pressure-boundary connections without engineering guidance.
