Value Collection 872271PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 872271PR is a hex socket cap screw designed for secure fastening in mechanical assemblies, structural connections, and general industrial applications. It features a 3/8-16 UNC thread profile and measures 3 inches in length under the head. The screw is partially threaded and driven with a 5/16-inch hex (Allen) key. Constructed from alloy steel with a zinc-plated coating, it offers good mechanical strength and basic corrosion resistance. This fastener is appropriate for machinists, maintenance technicians, and assembly professionals working in light to medium industrial environments.

This socket cap screw is suited for machine assembly, equipment maintenance, and fabrication work where a recessed drive fastener is required. The 3/8-16 UNC coarse thread is a widely used size in North American manufacturing and maintenance applications. Partial threading allows the unthreaded shank to act as a shoulder or locating surface in close-tolerance bores, making it useful in jigs, fixtures, and general mechanical assemblies.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 3-inch length under head suits deeper fastening applications
• Partially threaded shank provides a bearing surface in close-tolerance bores
• Alloy steel construction meets ASME B18.8 and ASTM A574 standards
• Zinc-plated finish provides basic corrosion protection in dry or mildly humid environments
• 5/16-inch hex drive accepts standard Allen keys and hex bit drivers

Compatibility

Designed as an OEM-style replacement or direct-use fastener for standard 3/8-16 UNC tapped holes in mechanical assemblies, equipment frames, and fabricated structures.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or thread-locking compound as required by the assembly specification. Follow applicable ASME or facility torque guidelines for 3/8-16 alloy steel fasteners.
