Value Collection HCI20870200G-010BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI20870200G-010BX is a fully threaded hex head bolt designed for general structural and mechanical fastening applications. It features a 7/8-9 UNC thread and a 2-inch length under head, manufactured from Grade 2 steel with a hot-dipped galvanized finish for corrosion resistance. The ASTM A307 designation confirms this bolt meets established standards for low-carbon steel fasteners used in a wide range of construction and industrial assemblies. Plumbers, electricians, HVAC technicians, and general contractors reach for this bolt when securing equipment, supports, brackets, and structural connections where reliable holding strength and corrosion protection are required.

This bolt is suited for residential and commercial applications including mechanical room equipment mounting, pipe support hangers, electrical panel framing, duct support assemblies, and general structural connections. The hot-dipped galvanized finish makes it appropriate for indoor and moderately corrosive outdoor environments. The fully threaded shank provides consistent thread engagement along the entire bolt length, which is useful when fastening into thick materials or when variable grip length is needed across different stack-ups.

Key Features

• 7/8-9 UNC thread for compatibility with standard inch-series nuts and tapped holes
• 2-inch length under head, fully threaded for maximum engagement flexibility
• Grade 2 steel construction meets ASTM A307 fastener standards
• Hot-dipped galvanized finish provides enhanced corrosion resistance over electroplated alternatives
• Hex head drive accepts standard wrenches and impact sockets

Compatibility

Designed as a standard inch-series hex head bolt compatible with 7/8-9 UNC nuts, washers, and tapped connections in general construction and mechanical fastening applications.

Installation Notes

Installation is performed by the appropriate trade for the assembly being secured, including HVAC technicians, plumbers, or electricians when mounting equipment and support structures. Always use a properly rated 7/8-9 nut and consider adding a flat washer to distribute load across the bearing surface. Verify that the galvanized finish is acceptable for the service environment, as some dissimilar metal contact situations may require additional isolation. Follow applicable codes such as the IBC or ASCE standards for structural fastener torque and installation requirements specific to the project.
