Value Collection HCI20873200G6 Hex Head Bolt 7/8-9 32 in

Product Description

The VALUE COLLECTION HCI20873200G6 is a 7/8-9 UNC hex head bolt with a 32-inch length under head, manufactured from Grade 2 steel with a hot-dipped galvanized finish. It is partially threaded and meets ASTM A307 standards. This bolt is designed for structural, mechanical, and general-purpose fastening applications where corrosion resistance and reliable clamping force are required. Installation is typically performed by millwrights, ironworkers, maintenance technicians, and general contractors working with steel connections, timber framing, or heavy equipment assemblies.

This bolt is suited for both indoor and outdoor applications where a hot-dipped galvanized coating is specified for corrosion protection. The large 32-inch length makes it appropriate for through-bolting thick timber, laminated lumber assemblies, steel fabrications, or bridge and infrastructure components. The partial threading allows the shank to act as a bearing surface in bolted connections, which is a common requirement in structural and mechanical joints.

Key Features

• 7/8-9 UNC thread size for use with standard 7/8-inch nuts and washers
• 32-inch length under head accommodates deep or stacked fastening applications
• Hot-dipped galvanized finish provides superior corrosion resistance over electroplated alternatives
• Partial threading leaves a smooth shank for shear-bearing connections
• Grade 2 steel meets ASTM A307 fastener standard for general structural use

Compatibility

Designed as a general-purpose hex head bolt compatible with standard 7/8-9 UNC threaded nuts, washers, and tapped holes in structural steel, timber, and heavy mechanical assemblies meeting ASTM A307 specifications.

Installation Notes

Installation is performed by qualified tradespeople including ironworkers, carpenters, or maintenance mechanics using standard hex wrenches or impact drivers fitted with the appropriate socket. Always verify that mating nuts, washers, and base materials are rated for the same grade and finish to avoid galvanic incompatibility. Consult applicable structural or mechanical codes, such as AISC or OSHA standards, for proper torque and connection requirements. Inspect the galvanized coating for damage before installation and apply cold galvanizing compound to any nicked areas.
