Value Collection HCI30870550NG-005BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI30870550NG-005BX is a heavy-duty hex head bolt designed for structural and industrial fastening applications. It features a 7/8-9 UNC thread with a 5.5-inch length under head and is partially threaded along the shank. Manufactured from steel to the A325 material grade and finished with a hot-dipped galvanized coating, this bolt is built to resist corrosion in demanding environments. It conforms to ASTM A325 standards, making it appropriate for structural steel connections and high-strength bolted assemblies. Licensed tradespeople and contractors working with structural steel rely on this grade for code-compliant connections.

This hex head bolt is suited for structural steel construction, heavy equipment fabrication, bridge work, and commercial or industrial building projects where high-strength fasteners are required. The partial threading is standard for structural bolted joints where the unthreaded shank bears the shear load. The hot-dipped galvanized finish extends service life in outdoor, high-humidity, and weather-exposed installations. Ironworkers, structural contractors, and mechanical contractors commonly specify A325 bolts for beam-to-column connections and similar load-bearing assemblies.

Key Features

• 7/8-9 UNC thread size for compatibility with standard structural hardware
• 5.5-inch length under head accommodates thicker structural members and connection stacks
• Partially threaded shank designed for shear-bearing structural joints
• Steel construction with A325 material grade for high-strength performance
• Hot-dipped galvanized finish provides enhanced corrosion resistance in outdoor and wet environments
• Meets ASTM A325 fastener standard for structural steel applications

Compatibility

Designed as an OEM-style structural fastener for use with standard 7/8-inch heavy hex nuts and washers in ASTM A325-compliant bolted connections.

Installation Notes

Installation should be performed by qualified ironworkers or structural contractors in accordance with the AISC specification and applicable local building codes. Shut down or isolate any energized equipment or live loads before working in the connection zone. Use calibrated torque wrenches or the turn-of-nut method as specified by the engineer of record — do not substitute arbitrary torque values. Inspect the galvanized coating for damage before installation and replace any bolts with compromised coating.
