Value Collection HCI30620175NG-010BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI30620175NG-010BX is a fully threaded hex head bolt designed for structural and heavy-duty fastening applications. It features a 5/8-11 UNC thread size, a length under head of 1-3/4 inches, and is manufactured from Grade A325 steel with a hot-dipped galvanized finish. The galvanized coating provides corrosion resistance for outdoor, exposed, or high-moisture environments. This bolt conforms to ASTM A325 standards, making it suitable for structural steel connections where load-rated fasteners are required. Ironworkers, structural steel contractors, and mechanical tradespeople install this type of fastener in bolted steel assemblies, equipment mounts, and framing connections.

This hex head bolt is well suited for structural steel fabrication, steel-to-steel connections, and general industrial fastening where ASTM A325 compliance is required. The fully threaded shank allows maximum thread engagement across the full bolt length, which is useful in thinner material stacks and applications requiring adjustable clamping depth. The hot-dipped galvanized finish makes this bolt appropriate for exterior construction, bridge components, and other corrosive environments where bare steel fasteners would degrade prematurely.

Key Features

• 5/8-11 UNC thread size for compatibility with standard heavy-duty hex nuts and structural hardware
• 1-3/4 inches length under head for precise fit in standard structural bolt patterns
• Fully threaded shank provides maximum thread engagement across the entire bolt length
• Grade A325 steel construction meets ASTM A325 structural bolt standards
• Hot-dipped galvanized finish delivers corrosion resistance in outdoor and high-moisture environments
• Weighs 0.177 pounds for straightforward handling and torque verification

Compatibility

Designed as an ASTM A325 structural hex head bolt for use with standard 5/8-11 heavy hex nuts and washers in structural steel and general industrial fastening assemblies.

Installation Notes

This bolt is installed by ironworkers or structural steel contractors following applicable AISC and RCSC specifications for structural bolted connections. Always use the correct grade-matched nut and hardened washer as required by the connection design. Torque requirements are determined by the engineer of record and the applicable connection specification — do not assume a torque value. Inspect the galvanized coating for damage before installation, as bare spots can compromise corrosion performance in exposed applications.
