The VALUE COLLECTION HCI31000600NG-005BX is a Grade A325 hex head bolt designed for structural and heavy-duty fastening applications. It features a 1-8 UNC thread and measures 6 inches in length under the head. Manufactured from steel with a hot-dipped galvanized finish, this bolt resists corrosion in demanding field conditions. The partial threading design provides full clamping force across the grip length, making it well-suited for structural steel connections. It conforms to ASTM A325 standards, which govern the mechanical requirements for high-strength structural bolts. Licensed tradespeople and structural ironworkers install this type of fastener in load-bearing assemblies.
This bolt is used in structural steel framing, heavy equipment mounting, bridge construction, and industrial base plate connections where high-strength fasteners meeting ASTM A325 requirements are specified. The hot-dipped galvanized finish makes it appropriate for exterior or high-moisture environments. It is sold individually and is intended for professional installation in applications governed by structural steel design codes and project specifications.
Designed as an OEM-style structural fastener for use with standard 1-8 UNC heavy hex nuts and hardened washers in ASTM A325-compliant structural steel assemblies.
Installation should be performed by qualified structural ironworkers or tradespeople following applicable structural steel specifications such as AISC and RCSC standards for high-strength bolted joints. Always use the specified hardened washers and compatible heavy hex nuts rated for A325 service. Torque or tension requirements are governed by the project engineer of record and applicable code — do not substitute values not listed in the project documents. Inspect the galvanized coating for damage before installation and avoid impact methods that may crack the zinc coating.
