Value Collection HCI30870275NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI30870275NG-005BX is a fully threaded hex head bolt rated to ASTM A325 structural steel standards. It features a 7/8-9 UNC thread size and a 2-3/4 inch length under head, finished with a hot-dipped galvanized coating for corrosion resistance. This bolt is manufactured from A325-grade steel, making it appropriate for high-strength structural connections where code-specified fastener ratings are required. It is installed by ironworkers, structural contractors, and millwrights on steel-to-steel connections in commercial, industrial, and infrastructure applications.

This bolt is suited for structural steel assemblies, heavy equipment mounting, and connection work where ASTM A325 fasteners are specified by engineers or governing codes. The 7/8-9 thread size is common in mid-to-heavy structural bolt patterns. The hot-dipped galvanized finish provides added protection in outdoor and exposed environments. The fully threaded shank allows engagement along the full grip length, which is practical in shorter bolt applications where thread engagement across the full length is required.

Key Features

• ASTM A325 structural bolt standard — meets high-strength fastener specifications
• 7/8-9 UNC thread for reliable engagement in standard structural applications
• Fully threaded shank — no unthreaded bearing surface, suitable for shorter grip lengths
• Hot-dipped galvanized finish for corrosion resistance in exposed or outdoor environments
• 2-3/4 inch length under head in inch measurement standard
• Steel construction with A325 material grade for high-strength load requirements

Compatibility

Designed as an ASTM A325-compliant hex head bolt for structural steel connections where 7/8-9 UNC fully threaded fasteners are specified.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural contractors following applicable code requirements, including AISC and RCSC specifications for structural bolt installation. Always confirm hole diameter, grip length, and nut compatibility before installation. Use calibrated torque tools or the turn-of-nut method as specified by the project engineer. Do not impact-drive A325 bolts without confirming the approved installation method for the connection type.
