Value Collection HCI30750750NG-005BX Hex Head Bolt 3/4-10

Product Description

The VALUE COLLECTION HCI30750750NG-005BX is a heavy-duty hex head bolt engineered for structural and industrial fastening applications. It features a 3/4-10 UNC thread size and measures 7.5 inches in length under the head, with partial threading along the shank. Constructed from A325 grade steel with a hot-dipped galvanized finish, this bolt meets ASTM A325 structural standards, making it suitable for high-strength bolted connections in steel-to-steel assemblies. Weighing 1.244 pounds per unit, it delivers the mass and mechanical integrity that structural trades demand on heavy-duty jobsites.

This bolt is used in structural steel construction, heavy equipment fabrication, bridge work, and commercial building framing where ASTM A325 compliance is specified. It is installed by ironworkers, structural steel contractors, and millwrights working on bolted moment connections, flange joints, and beam-to-column connections. The partially threaded shank is particularly suited for applications requiring a smooth bearing surface in the grip zone, such as slip-critical and bearing-type connections governed by AISC and RCSC bolt specifications.

Key Features

• ASTM A325 structural grade steel for high-strength bolted connections
• Hot-dipped galvanized finish provides corrosion resistance for outdoor and exposed applications
• Partially threaded shank maintains full grip-zone bearing surface
• 3/4-10 UNC thread form ensures compatibility with standard structural nuts and washers
• 7.5 inch length under head accommodates thick steel stack-ups
• Inch measurement system for use with standard imperial hardware

Compatibility

Designed for use with 3/4-10 UNC heavy hex nuts and hardened washers meeting ASTM F436 or equivalent structural standards, as required by ASTM A325 bolted assembly specifications.

Installation Notes

Installation should be performed by qualified ironworkers or structural steel mechanics in accordance with RCSC Specification for Structural Joints Using High-Strength Bolts. Power down and de-energize any adjacent electrical systems before working in proximity to energized panels or bus structures. Use calibrated torque wrenches or tension-control tooling appropriate for 3/4-inch A325 fasteners as required by the project engineer of record. Inspect threads and galvanized coating for damage before installation; do not install bolts with stripped threads or compromised coating.
