Value Collection HCI31120325NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31120325NG-005BX is a fully threaded hex head bolt designed for structural and heavy-duty fastening applications. It features a 1-1/8-7 UNC thread and measures 3-1/4 inches in length under the head. Manufactured from A325 structural steel with a hot-dipped galvanized finish, this bolt delivers corrosion resistance suitable for outdoor and high-humidity environments. It meets ASTM A325 standards, making it appropriate for structural steel connections where specification-grade fasteners are required. Installation is performed by ironworkers, structural contractors, and maintenance professionals working on steel assemblies.

This bolt is suited for structural steel framing, heavy equipment mounting, and connection work where ASTM A325 specification compliance is required. The fully threaded design accommodates a range of engagement depths and is commonly used in residential, commercial, and industrial steel construction. The hot-dipped galvanized finish provides an added layer of protection in exposed or corrosive environments compared to standard zinc-plated alternatives.

Key Features

• 1-1/8-7 UNC thread form for compatibility with standard structural nuts and hardware
• Fully threaded shank allows flexible engagement depth across varied connection thicknesses
• Hot-dipped galvanized finish provides enhanced corrosion resistance over electroplated coatings
• Meets ASTM A325 structural bolt standard for use in specification-driven steel connections
• 3-1/4 inch length under head suits a range of steel connection stack-ups
• Weight of 1.95 pounds per package quantity of 1 bolt reflects the substantial cross-section of this large-diameter fastener

Compatibility

Designed as an OEM-style structural replacement fastener for applications requiring ASTM A325 grade bolts with a 1-1/8-7 UNC thread and 3-1/4 inch length under head in steel construction assemblies.

Installation Notes

Installation of structural A325 bolts should be performed by qualified ironworkers or structural contractors in accordance with AISC and RCSC specifications for structural bolting. Power down and de-energize any nearby electrical equipment before working in proximity to energized systems. Torque or tension requirements must follow the applicable project specification or engineer of record guidance. Do not substitute non-specification-grade hardware in structural connections governed by engineering drawings.
