Value Collection 837375PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 837375PR is a partially threaded hex socket cap screw designed for high-strength fastening applications. It features a 1/2-13 UNC thread size, a 3-1/2 inch length under head, and a 3/8 inch hex drive. Constructed from alloy steel with a zinc-plated finish for corrosion resistance, this fastener meets ASTM B695 standards. It is installed using a hex key or socket driver and is suited for mechanical assemblies, structural connections, and equipment fabrication where a recessed drive and controlled clamping force are required.

This screw is used across industrial, commercial, and heavy-duty maintenance applications. The partial threading allows for a strong grip in thick materials while the socket cap head provides a clean, low-profile installation in countersunk or clearance-hole assemblies. Machinists, millwrights, maintenance technicians, and general contractors commonly specify this fastener in steel-to-steel and steel-to-plate joints where torque consistency and head strength matter.

Key Features

• 1/2-13 UNC thread for compatibility with standard inch-series tapped holes
• 3-1/2 inch length under head accommodates thicker material stacks
• Partially threaded shank provides shear strength and precise clamping in deep assemblies
• 3/8 inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction delivers high tensile and yield strength
• Zinc-plated finish meets ASTM B695 for corrosion protection in typical indoor and light industrial environments

Compatibility

Designed as an OEM-style replacement or direct-specification fastener for standard 1/2-13 UNC tapped holes in steel assemblies and mechanical equipment requiring a hex socket cap screw with partial threading.

Installation Notes

Installation is performed using a 3/8 inch hex key or socket driver. Always ensure the mating tapped hole is clean and free of debris before threading. Follow applicable torque specifications from your engineering or equipment documentation for 1/2-13 UNC alloy steel fasteners. Do not use an impact driver without a torque-limiting mechanism, as over-torquing can damage threads or the fastener head.
