Value Collection 454604BR Hex Head Cap Screw 7/8-9 X 6 in

Product Description

The VALUE COLLECTION 454604BR is a fully threaded hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating for corrosion resistance, this fastener measures 7/8-9 thread size with a 6-inch length under head. It conforms to ASME B18.2.1 and SAE J429 standards, making it a code-compliant choice for demanding load-bearing connections. The 7/8-9 UNC thread pattern provides high tensile strength and reliable engagement in threaded holes or with compatible nuts.

This cap screw is suited for use in heavy equipment, machinery frames, structural steel connections, and fabrication work where Grade 8 strength is required. Fully threaded along the 6-inch shank, it works well in through-bolt applications or in assemblies requiring maximum thread engagement. Electricians, millwrights, pipefitters, and general contractors commonly specify Grade 8 fasteners like this one for high-stress joints in both commercial and industrial settings.

Key Features

• Grade 8 steel construction for high tensile and proof load strength

• Fully threaded shank maximizes thread engagement across the full 6-inch length
• 7/8-9 UNC thread standard ensures broad compatibility with standard nuts and tapped holes
• Meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards
• 1-5/16 inch hex key size for use with standard wrenches and sockets

Compatibility

Designed for use in standard 7/8-9 UNC threaded applications requiring Grade 8 strength and ASME B18.2.1 and SAE J429 compliance.

Installation Notes

Installation should be performed by a qualified tradesperson using a properly sized 1-5/16 inch wrench or socket. Follow applicable torque specifications from engineering drawings or fastener standards guides for Grade 8 hardware at this thread size. Ensure mating threads are clean and free of debris before installation. Do not mix thread standards or grades when assembling critical joints.
