Value Collection 872367PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 872367PR is a hex socket cap screw designed for fastening applications that require a recessed drive and high clamping strength. This partially threaded cap screw carries a 1/2-13 UNC thread size and a 2.5-inch length under head. It is machined from alloy steel and finished with a zinc-plated coating for corrosion resistance. The 3/8-inch hex drive accepts a standard hex key or Allen-style socket. This fastener meets ASME B18.8 and ASTM A574 standards, making it suitable for structural and mechanical assembly work across industrial and trade applications.

This screw is used in general mechanical assembly, machinery maintenance, and structural fastening tasks where a flush or low-profile head is required. Partial threading allows the unthreaded shank to provide shear strength and precise positioning in clearance holes. Typical applications include equipment fabrication, fixture assembly, and maintenance of mechanical systems in commercial and industrial settings. Licensed millwrights, machinists, pipefitters, and maintenance technicians commonly install this fastener type.

Key Features

• 1/2-13 UNC thread for compatibility with standard inch-series tapped holes
• 2.5-inch length under head with partial threading for shear-load applications
• 3/8-inch hex socket drive for use with common Allen keys or hex socket tools
• Alloy steel construction meeting ASTM A574 for high tensile and proof load ratings
• Zinc-plated finish provides baseline corrosion protection in dry to mildly humid environments
• Conforms to ASME B18.8 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 1/2-13 UNC partially threaded hex socket cap screw with a 2.5-inch length under head.

Installation Notes

Installation is performed using a 3/8-inch hex key or Allen-style socket driver. Always ensure the mating tapped hole is clean and free of debris before threading. Follow the equipment manufacturer's torque specifications for the assembly being serviced, as no specific torque value is defined by fastener dimensions alone. Power down and de-energize any equipment before accessing fastener locations on mechanical assemblies.
