Value Collection D39122 Hex Cap Screw 1/2-13 X 7 in Grade 8

Product Description

The VALUE COLLECTION D39122 is a partially threaded hex head cap screw designed for heavy-duty mechanical and structural fastening applications. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers high tensile strength and corrosion resistance suitable for demanding industrial environments. The 1/2-13 thread size follows the Unified National Coarse (UNC) standard, and the 7-inch length under head accommodates thick material stacks where a full-thread fastener would be unsuitable. Meets ASME B18.2.1 and SAE J429 standards. Sold individually with a minimum order quantity of 10 units.

This fastener is commonly used in industrial machinery assembly, structural steel fabrication, equipment mounting, and heavy mechanical applications where high-strength fasteners are required. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for bolted joints where precise load distribution matters. Tradespeople in mechanical, construction, and maintenance fields rely on Grade 8 hex cap screws for connections that must hold under vibration and dynamic loading.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength
• Zinc yellow dichromate finish offers corrosion resistance in moderate-exposure environments
• Partially threaded shank supports shear load applications
• 1/2-13 UNC thread ensures broad compatibility with standard hex nuts and tapped holes
• Meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, lock nuts, and tapped holes conforming to inch-series fastener standards. Suitable as a replacement or stocking fastener in any application requiring a Grade 8, 1/2-13 x 7-inch partially threaded hex cap screw.

Installation Notes

Installation should be performed by qualified mechanical or maintenance tradespeople using an appropriate torque wrench and socket. Always clean and inspect mating threads before assembly. Follow applicable industry torque specifications for Grade 8 fasteners at this thread size as defined by your project or equipment standards. Do not reuse fasteners that show signs of thread damage, galling, or deformation.
