Value Collection HCI20870225G Hex Head Bolt 7/8-9 Grade 2

Product Description

The VALUE COLLECTION HCI20870225G is a 7/8-9 hex head bolt designed for general structural and mechanical fastening applications. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt provides corrosion resistance suited to outdoor, wet, or exposed environments. It is fully threaded along its 2.25-inch length under head, measured from the bearing surface to the tip, conforming to UNC thread standards and certified to ASTM A307. Electricians, plumbers, HVAC installers, and general contractors reach for this bolt when assembling equipment pads, pipe supports, structural brackets, and similar trade hardware requiring a reliable inch-series fastener.

This bolt is appropriate for light to moderate structural fastening in both residential and commercial settings. Its hot-dipped galvanized coating makes it a practical choice for outdoor mechanical rooms, rooftop equipment mounting, conduit and pipe hanger assemblies, and any application where base steel would be exposed to moisture or corrosive conditions. Full threading along the shank allows engagement across the full grip range, offering flexibility when working with varying material stack thicknesses.

Key Features

• 7/8-9 UNC thread size for broad compatibility with standard inch-series nuts and tapped holes
• Fully threaded shank allows maximum grip range flexibility
• Hot-dipped galvanized finish provides corrosion resistance in wet and outdoor environments
• Grade 2 steel construction meets ASTM A307 fastener standard
• 2.25-inch length under head suits medium-depth structural connections

Compatibility

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

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 7/8-9 bolt head. Always de-energize and lock out any equipment before installing fasteners on live mechanical or electrical assemblies. Use appropriate flat and lock washers to prevent loosening under vibration. Follow applicable structural or mechanical codes when used in load-bearing connections.
