Value Collection HCI50870700G Hex Cap Screw 7/8-9 X 7 in

Product Description

The VALUE COLLECTION HCI50870700G is a partially threaded hex head cap screw sized 7/8-9 x 7 inches, manufactured from Grade 5 steel with a hot-dipped galvanized finish. The UNC thread profile and hot-dipped galvanizing make this fastener well suited for outdoor, structural, and industrial applications where corrosion resistance matters. The 7/8-9 designation indicates a 7/8-inch nominal diameter with 9 threads per inch. This is a standard inch-system fastener used by ironworkers, millwrights, structural steel contractors, and maintenance mechanics in general industrial assembly.

This cap screw is appropriate for structural connections, equipment mounting, and heavy-duty fastening tasks in both commercial and industrial environments. The partial threading allows for a smooth shank section beneath the head, which is preferred when the fastener passes through clearance holes in stacked material before engaging the threaded section. Applications include frame assembly, machinery bases, steel fabrication, and utility infrastructure work.

Key Features

• Grade 5 steel construction provides tensile strength suited for structural and mechanical fastening
• Hot-dipped galvanized finish delivers corrosion resistance for outdoor and wet-environment use
• 7/8-9 UNC thread standard ensures broad compatibility with standard nuts and tapped holes
• Partially threaded shank reduces thread engagement in clearance zones for cleaner clamping
• 7-inch length under head accommodates thick material stacks and long-grip applications
• Inch system measurement throughout for direct use with standard SAE tooling

Compatibility

Designed for use with standard 7/8-9 UNC hex nuts, washers, and tapped holes conforming to inch-system UNC thread standards.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural or mechanical codes. Use a properly sized hex socket or open-end wrench rated for the fastener torque class. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not exceed the torque limits for Grade 5 fasteners as specified in the applicable ASME or project engineering documents.
