Value Collection MP30597 Hex Head Cap Screw 3/8-16 Grade 316

Product Description

The VALUE COLLECTION MP30597 is a 3/8-16 UNC hex head cap screw measuring 2-1/4 inches in length under the head. Manufactured from Grade 316 stainless steel with no surface coating applied, this fastener delivers solid corrosion resistance in wet, chemical-exposed, or marine environments where standard carbon steel hardware is not suitable. The partially threaded shank allows for precise clamping force in bolted assemblies. Installed by millwrights, pipefitters, plumbers, and maintenance technicians, this screw is a standard inch-system fastener used across industrial, mechanical, and trade applications.

This cap screw is suited for use in corrosive environments including HVAC equipment mounting, plumbing system assemblies, pool and water treatment equipment, and general mechanical applications where Grade 316 stainless steel is specified. The UNC thread form is the most common coarse-thread standard in inch-system fastener applications, making this screw widely compatible with standard tapped holes and hex nuts of the matching thread class.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 3/8-16 UNC coarse thread — standard inch-series thread for broad compatibility
• 2-1/4 inch length measured under the head
• Partially threaded shank for controlled clamping in bolted joint assemblies
• Uncoated finish — no plating or coating that could compromise corrosion performance or dimensional tolerance
• Hex head drive accepts standard hex wrenches and sockets

Compatibility

Designed as a standard 3/8-16 UNC inch-series hex head cap screw for use with matching 3/8-16 threaded holes, nuts, and inserts in mechanical and trade assemblies requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation is performed by hand-threading the fastener fully before applying torque with a standard hex wrench or socket. Power down or depressurize any system before replacing fasteners in live mechanical assemblies. Do not mix stainless steel fasteners with dissimilar metals in submerged or highly conductive environments without evaluating galvanic corrosion risk. Follow applicable mechanical codes and equipment manufacturer torque specifications for the joint being assembled.
