Value Collection 837357PS Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 837357PS is a fully threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This screw features a 1/2-13 UNC thread size and a 1-1/4 inch length under head, providing reliable clamping force in medium-depth fastening situations. The 3/8 inch hex drive socket interface allows precise torque application using a standard hex key or Allen wrench. Constructed from alloy steel with a zinc-plated finish, this fastener resists corrosion and offers the tensile strength required for demanding environments. Machinists, maintenance technicians, and fabricators regularly specify this type of fastener for machine assembly and equipment maintenance work.

This hex socket cap screw is suited for use in manufacturing, fabrication shops, general industrial maintenance, and mechanical assembly operations where a flush or recessed fastener profile is required. The UNC thread form is the standard coarse-thread designation widely used across North American industry. Its zinc-plated coating makes it appropriate for dry to mildly corrosive indoor environments. The fastener meets ASTM B695 standards, making it a dependable choice for applications with defined finish coating requirements.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 1-1/4 inch length under head for medium-depth fastening applications
• 3/8 inch hex socket drive for precise torque application with a hex key
• Fully threaded shank maximizes thread engagement in through-hole and shallow-hole assemblies
• Alloy steel construction delivers high tensile and shear strength
• Zinc-plated finish meets ASTM B695 for corrosion resistance in indoor environments

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any application requiring a coarse-thread, socket-drive fastener of this thread size and length specification.

Installation Notes

Installation requires a 3/8 inch hex key or Allen wrench of appropriate length and quality for the torque load involved. Always clean and inspect mating threads before installation to avoid cross-threading or galling. Power down and de-energize any equipment before replacing or tightening fasteners in live assemblies. Follow the applicable industry or equipment manufacturer torque specifications for 1/2-13 UNC alloy steel fasteners when final torque values are required.
