Value Collection HCI30870250NG-005BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI30870250NG-005BX is a fully threaded hex head bolt designed for structural and general fastening applications. It features a 7/8-9 UNC thread size with a 2-1/2 inch length under head, manufactured from Grade A325 steel with a hot-dipped galvanized finish for corrosion resistance. This bolt meets ASTM A325 standards, making it suitable for structural steel connections and heavy-duty mechanical assemblies. The hot-dipped galvanized coating provides reliable protection in exposed or moisture-prone environments. Installation requires standard hex tooling and is typically performed by ironworkers, millwrights, structural contractors, or maintenance trades working with bolted steel connections.

This bolt is used in structural steel fabrication, equipment mounting, and heavy-duty fastening applications where ASTM A325 compliance is required. The fully threaded configuration provides uniform thread engagement along the entire shank, which suits applications with varying grip lengths or where nuts must be positioned anywhere along the bolt length. It fits residential, commercial, and industrial construction scenarios where galvanized structural fasteners are specified.

Key Features

• 7/8-9 UNC thread size with 2-1/2 inch length under head
• Fully threaded shank for flexible nut positioning along full bolt length
• Hot-dipped galvanized finish for corrosion resistance in exposed environments
• Grade A325 steel construction meeting ASTM A325 structural bolt standards
• Inch measurement system with standard hex head drive interface

Compatibility

Designed as a standard ASTM A325 structural hex head bolt for use with 7/8-9 UNC nuts and washers in bolted steel connections conforming to ASTM A325 specifications.

Installation Notes

Installation of structural A325 bolts should be performed by qualified tradespeople following applicable structural codes, including AISC and RCSC specifications for high-strength bolted connections. Shut down and de-energize any adjacent systems before working in confined structural assemblies. Proper torque must be applied per the relevant connection specification; do not substitute impact-only installation where snug-tight or pretensioned assembly is required. Inspect the galvanized coating for damage before installation and replace any fastener showing compromised coating in corrosive service environments.
