Value Collection 97124 Hex Head Cap Screw 1/2-13 X 8 in Grade 5

Product Description

The VALUE COLLECTION 97124 is a Grade 5 steel hex head cap screw sized at 1/2-13 thread by 8 inches under the head. It follows a Unified National Coarse (UNC) thread standard and is partially threaded along the shank. The bright, uncoated finish leaves the steel bare with no added plating or coating. This fastener meets ASME B18.2.1 dimensional standards, making it a reliable choice for structural and mechanical assembly work in industrial, commercial, and trade applications. Maintenance technicians, pipefitters, millwrights, and general contractors commonly use this size in equipment mounting, structural steel connections, and heavy-duty mechanical assemblies.

This hex head cap screw is suited for bolted connections where a standard UNC thread pattern and partial threading are required. The 1/2-13 thread size and 8-inch length under the head make it appropriate for thicker material stackups and longer-reach fastening applications. It is a straight-inch-system fastener, compatible with standard SAE hex drivers and sockets. Typical applications include machinery mounting, framing connections, and general structural assembly in residential, commercial, and light industrial settings.

Key Features

• Grade 5 steel construction for reliable tensile and yield strength in structural and mechanical fastening
• 1/2-13 UNC thread - a widely used coarse thread size compatible with standard nuts and tapped holes
• 8 inches under the head - suitable for thick material stackups and extended-reach bolted connections
• Partially threaded shank provides a smooth bearing surface and improved shear resistance
• Bright, uncoated finish - no plating to interfere with grounding applications or galvanic concerns where coating is undesirable
• Meets ASME B18.2.1 dimensional standard for consistent head geometry and thread form

Compatibility

Designed as an OEM-style replacement or general-use hex head cap screw for any application requiring a 1/2-13 UNC, 8-inch, Grade 5, partially threaded fastener conforming to ASME B18.2.1.

Installation Notes

Installation is performed with a standard 3/4-inch hex drive socket or wrench. Always ensure the mating nut or tapped hole matches the 1/2-13 UNC thread specification before installation. Follow applicable torque requirements per the equipment manufacturer or governing code for the assembly type. Inspect threads for damage and verify the joint is free of contamination before torquing to final specification.
