Value Collection D39114 Hex Head Cap Screw 1/2-13 Grade 8

Product Description

The Value Collection D39114 is a Grade 8 steel hex head cap screw with a 1/2-13 UNC thread and a 3-1/2 inch length under head. It is partially threaded and finished with a zinc yellow dichromate coating, which provides corrosion resistance and meets ASME B18.2.1 standards. This fastener is suited for high-strength bolted joint applications where a reliable, standardized cap screw is required. It is installed by maintenance technicians, millwrights, mechanical contractors, and tradespeople working on structural assemblies, machinery, and equipment.

This cap screw is used in general industrial, commercial, and trade applications where Grade 8 strength and inch-series UNC threading are specified. Its partial threading is appropriate for grip-length requirements in bolted connections where the shank must bear shear loads or maintain precise clamping across joined materials. Suitable for use in mechanical, HVAC equipment mounting, and structural hardware applications.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• 1/2-13 UNC thread standard, inch-series measurement system
• 3-1/2 inch length under head with partial threading for shear-bearing shank
• Zinc yellow dichromate finish for corrosion resistance
• Meets ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw compatible with any application specifying a 1/2-13 UNC partially threaded Grade 8 fastener.

Installation Notes

Install using a properly sized hex wrench or socket drive rated for Grade 8 fastener torque requirements. Always verify thread engagement and mating nut or tapped hole specification before installation. Consult the equipment manufacturer torque table or applicable mechanical code for the correct clamp load. Do not mix inch and metric fasteners in the same joint assembly.
