Value Collection 837271PS Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 837271PS is a hex socket cap screw designed for fastening applications requiring reliable clamping force and a low-profile head. Sized at 3/8-16 UNC with a 3-inch length under head, this screw is partially threaded and driven with a 5/16-inch hex key. It is manufactured from alloy steel with a zinc-plated finish that provides basic corrosion resistance. This fastener meets ASTM B695 standard and is suited for mechanical assembly, structural mounting, and equipment fabrication work performed by machinists, maintenance technicians, and industrial assembly professionals.

This screw is used in a wide range of industrial, mechanical, and trade applications where a recessed hex drive and high-strength alloy steel construction are required. The partial threading allows for free-spinning through clearance holes before engaging a threaded bore or nut, which is common in bolted joint assemblies, machine frames, fixtures, and general metalwork. It is well suited for both shop and field installation scenarios where controlled torque and fastener integrity are critical.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard inch-series tapped holes and nuts
• 3-inch length under head provides adequate grip length for thick-section assemblies
• Partially threaded shank allows smooth passage through clearance holes before thread engagement
• 5/16-inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction delivers high tensile and shear strength
• Zinc-plated finish per ASTM B695 for basic corrosion protection in mild environments

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes and mating hex nuts across general industrial, mechanical, and structural fastening applications.

Installation Notes

Installation is performed with a 5/16-inch hex key or socket driver. Ensure the mating threaded bore or nut is clean and free of debris before driving. Do not exceed the rated torque for the fastener grade and material being clamped. Always de-energize or isolate any equipment before performing fastening work on mechanical assemblies.
