Value Collection HCI20870600G Hex Head Bolt 7/8-9 6in Grade 2

Product Description

The VALUE COLLECTION HCI20870600G is a 7/8-9 hex head bolt with a 6-inch length under head, manufactured from Grade 2 steel with a hot-dipped galvanized finish. Partially threaded along its shank, this bolt conforms to ASTM A307 standards, making it a reliable general-purpose fastener for structural and mechanical applications. Weighing approximately 1 pound, it is suited for use in applications where corrosion resistance is required from the galvanized coating. Electricians, plumbers, HVAC technicians, and general contractors routinely use bolts of this type when securing equipment, frames, brackets, and structural assemblies in both indoor and outdoor environments.

This bolt is appropriate for use in residential and commercial construction, mechanical equipment mounting, pipe hangers, structural steel connections, and utility installations. The UNC (Unified National Coarse) thread standard ensures broad compatibility with standard hex nuts, washers, and tapped holes sized for 7/8-9 threading. The hot-dipped galvanized finish provides added protection in damp or outdoor conditions compared to plain or zinc-plated alternatives.

Installation Notes

Install using the appropriate wrench or socket sized for a 7/8-inch hex head bolt. Always use a properly rated nut and washer combination matched to the ASTM A307 Grade 2 specification. Verify thread engagement depth meets the requirements of the applicable building or mechanical code before torquing. Do not use impact drivers at high speed on galvanized fasteners without confirming coating integrity after installation.
