Value Collection HCI31250350NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31250350NG-005BX is a fully threaded hex head bolt engineered for structural and heavy-duty fastening applications. It is manufactured from steel to ASTM A325 material grade standards and features a hot-dipped galvanized finish for corrosion resistance. The thread size is 1-1/4-7 UNC with a length under head of 3.5 inches. Weighing 2.635 pounds per package quantity of five, this bolt is suited for use by ironworkers, structural steel erectors, and contractors working on bolted connections that demand high-strength fasteners with proven load capacity.

This bolt is used in structural steel connections, heavy equipment assembly, and industrial fastening where ASTM A325 compliance is required. Its fully threaded configuration provides consistent engagement along the entire shank length, making it well suited for through-bolting applications and connections where nut positioning varies. The hot-dipped galvanized finish adds durability in outdoor, exposed, or high-humidity environments where bare steel fasteners would be subject to accelerated corrosion.

Key Features

• ASTM A325 rated for high-strength structural bolting applications
• Fully threaded along the entire shank for flexible nut placement
• Hot-dipped galvanized finish provides corrosion protection in exposed environments
• 1-1/4-7 UNC thread size for compatibility with standard structural hardware
• 3.5 inches length under head for through-bolting and thick-member connections
• Inch measurement system for use with standard imperial tooling and hardware

Compatibility

Designed as an ASTM A325 compliant structural hex head bolt for use with standard 1-1/4-7 UNC nuts and washers in heavy-duty bolted steel connections.

Installation Notes

Installation should be performed by qualified ironworkers or structural contractors following applicable codes, including AISC and RCSC specifications for structural bolting. Power down any adjacent energized systems before working in proximity to electrical infrastructure. Use calibrated torque wrenches or tension control tooling as required by project specifications. Do not substitute A325 hardware in applications requiring A490 or higher-grade fasteners without engineering review.
