Value Collection D39131 Hex Cap Screw 9/16-12 Grade 8

Product Description

The VALUE COLLECTION D39131 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built to Grade 8 specifications, this fastener delivers tensile strength suited for demanding bolted connections where hardware integrity is critical. The 9/16-12 thread designation indicates a 9/16-inch nominal diameter with 12 threads per inch on a Unified National Coarse (UNC) thread form. The 1.5-inch length is measured under the head. A zinc yellow dichromate finish provides corrosion resistance and meets ASME B18.2.1 dimensional standards. Licensed trades and maintenance professionals rely on this fastener class for equipment mounting, machinery assembly, and structural bracketing work.

This cap screw is suited for use in heavy equipment, industrial machinery, automotive, and general fabrication applications where Grade 8 hardness is specified. The fully threaded shaft allows engagement along the entire shank length, making it well-suited for shorter grip lengths and applications requiring maximum thread engagement. Installers working in maintenance, millwright, or mechanical contracting trades will find this fastener fits standard 9/16-inch hardware configurations. Minimum order quantity is 10 pieces.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank allows maximum thread engagement across the full 1.5-inch length under head
• 9/16-12 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• Meets ASME B18.2.1 dimensional standards for hex head cap screws

Compatibility

Designed as an OEM-style replacement or standard-stock hex head cap screw for use with 9/16-12 UNC inch-series nuts, washers, and tapped holes in steel and iron assemblies.

Installation Notes

Installation is performed by mechanical, millwright, or maintenance trades using standard hex wrenches or socket sets sized for 9/16-inch hex cap screws. Always verify thread engagement depth and mating thread condition before final torque. Follow applicable equipment service manuals or structural specifications for torque values, as none are specified here. Inspect the zinc finish for damage before installation in corrosive environments.
