Value Collection HCI30620325NG-010BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620325NG-010BX is a 5/8-11 UNC hex head bolt manufactured from A325-grade steel with a hot-dipped galvanized finish. The bolt measures 3.25 inches in length under the head and features partial threading, making it suited for structural and heavy-duty fastening applications where a bearing-length shank is required. At 0.24 pounds, this is a single-piece unit sold individually. It meets ASTM A325 standards, the specification governing structural bolts for use in steel construction and high-strength connections. Licensed tradespeople and structural contractors select this bolt for applications where load-bearing performance and corrosion resistance are both critical requirements.

This hex head bolt is used in structural steel connections, heavy equipment assembly, and general industrial fastening where ASTM A325 compliance is specified. The hot-dipped galvanized coating provides enhanced corrosion resistance suitable for outdoor, exposed, or mildly corrosive environments. Partial threading leaves a smooth shank section beneath the head, which is standard practice in shear-critical bolted joints. Iron workers, structural steel erectors, and commercial construction trades typically install these fasteners per applicable building codes and project specifications.

Key Features

• 5/8-11 UNC thread size for compatibility with standard hex nuts and structural connection hardware
• 3.25 inches length under head with partial threading for shear-critical bolted joints
• A325-grade steel construction meets ASTM A325 structural bolt standard
• Hot-dipped galvanized finish provides corrosion resistance for outdoor and exposed installations
• Inch measurement system with standard UNC thread form

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use with standard 5/8-11 UNC hex nuts and washers in structural steel and heavy-duty fastening applications.

Installation Notes

Installation should be performed by qualified ironworkers or structural trades following applicable building codes and project engineering specifications. Torque values must be sourced from the engineer of record or applicable AISC and RCSC specifications for A325 fasteners. Always use appropriate flat washers under the bolt head and nut as required by the connection design. Inspect the galvanized coating for damage before installation and do not mix with non-compatible fastener grades in the same connection.
