Value Collection HCI20870550G-010BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI20870550G-010BX is a 7/8-9 partially threaded hex head bolt designed for structural and general fastening applications. It measures 5.5 inches in length under the head and is manufactured from Grade 2 steel with a hot-dipped galvanized finish for corrosion resistance. Conforming to ASTM A307 standards, this bolt is suited for low-carbon steel fastening work where moderate tensile strength and weather exposure resistance are required. It is sold individually and is appropriate for use by tradespeople, contractors, and maintenance professionals working with standard inch-series fasteners.

This bolt is commonly used in light structural assemblies, equipment mounting, and general construction fastening where UNC thread engagement and galvanized corrosion protection are specified. The 7/8-9 UNC thread profile is a standard inch-series coarse thread, making it compatible with standard hex nuts, washers, and tapped holes of matching specification. Hot-dipped galvanizing provides a thick zinc coating suited for outdoor and corrosive environments compared to standard zinc plating.

Compatibility

Designed as a standard inch-series hex head bolt for use with 7/8-9 UNC hex nuts, flat washers, and lock washers in general structural and mechanical fastening applications.

Installation Notes

Installation of structural bolts should be performed by qualified tradespeople in accordance with applicable building codes and AISC or similar structural standards. Verify thread engagement and mating hardware specifications before installation. Avoid over-torquing Grade 2 fasteners, as they have lower proof load ratings than Grade 5 or Grade 8 equivalents. Inspect the galvanized coating for damage before use in corrosive environments.
