Value Collection HCI31000650NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000650NG-005BX is a 1-8 UNC hex head bolt manufactured from Grade A325 steel with a hot-dipped galvanized finish. It measures 6.5 inches in length under the head and features partial threading, conforming to ASTM A325 structural bolt standards. Weighing 2.158 pounds, this bolt is built for heavy structural applications where high tensile strength and corrosion resistance are required. Licensed contractors, ironworkers, and structural tradespeople working on steel connections, building frames, and infrastructure projects are the primary installers of this fastener.

This bolt is suited for structural steel connections in commercial and industrial construction environments. The ASTM A325 specification designates it as a high-strength fastener appropriate for use in bolted steel joints, including beam-to-column connections and other load-bearing assemblies. The hot-dipped galvanized finish provides added corrosion protection, making it viable in exterior and exposed structural applications where moisture and environmental exposure are concerns.

Key Features

• Grade A325 steel construction meets ASTM A325 high-strength structural bolt standards
• Hot-dipped galvanized finish provides durable corrosion resistance for exterior use
• 6.5-inch length under head accommodates thick structural steel connection stacks
• 1-8 UNC thread size for compatibility with standard structural nuts and washers
• Partially threaded shank preserves shear strength in the bolt grip zone

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use in standard inch-series bolted steel connections where high-strength fasteners are specified.

Installation Notes

Installation of ASTM A325 structural bolts must be performed by qualified tradespeople following applicable structural codes, including AISC and RCSC specifications for high-strength bolted connections. Always use appropriate hardened washers and A563 heavy hex nuts rated for A325 applications. Torque or tension values must be determined per project engineering specifications and are not specified here. Never reuse A325 structural bolts once they have been fully tensioned, as this may compromise structural integrity.
