Value Collection 837261PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 837261PR is a hex socket cap screw designed for mechanical fastening applications requiring a recessed drive and a high-strength steel construction. It features a 3/8-16 UNC thread size with a 1-3/4 inch length under the head and is partially threaded. The drive is a 5/16 inch hex socket, compatible with standard Allen or hex key drivers. Finished with a zinc plating per ASTM B695, it offers baseline corrosion resistance for general-purpose use. This fastener is suited for assembly and maintenance work across industrial, mechanical, and trade service environments.

This screw is a standard choice for bolting flanges, mounting brackets, machine components, and structural assemblies where a flush or low-profile head is required. The partial thread allows for precise clamping force between two or more parts without thread engagement in the grip length zone. It is commonly used by millwrights, maintenance technicians, pipefitters, and general contractors working on equipment assembly or fabrication tasks requiring UNC-threaded fasteners in alloy steel.

Key Features

• 3/8-16 UNC thread for wide compatibility with standard inch-series tapped holes
• 1-3/4 inch length under head with partial threading for reliable clamping grip
• 5/16 inch hex socket drive for use with Allen wrenches or hex bit drivers
• Alloy steel construction for higher tensile strength compared to standard carbon steel
• Zinc-plated finish meeting ASTM B695 for corrosion protection in general service environments

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use in any application with a matching UNC tapped hole or nut, including mechanical assemblies, structural brackets, and equipment mounting applications.

Installation Notes

Installation is typically performed by a mechanic, millwright, or maintenance technician using a hex key or hex bit driver sized to 5/16 inch. Ensure the mating tapped hole or nut is clean and free of debris before threading the fastener. Apply the appropriate torque per the assembly specification for 3/8-16 alloy steel fasteners. Do not mix UNC and UNF fasteners in the same tapped hole.
