Value Collection HCI31000750NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000750NG-005BX is a heavy-duty hex head bolt manufactured from A325-grade steel with a hot-dipped galvanized finish. It features a 1-8 UNC thread size and measures 7.5 inches in length under the head with partial threading along the shank. Rated to ASTM A325 structural fastener standards, this bolt is designed for high-strength applications where corrosion resistance and load-bearing reliability are required. Weighing approximately 2.378 pounds per unit, it is suited for demanding structural and mechanical assemblies. Installation is typically performed by ironworkers, millwrights, structural contractors, and commercial construction trades.

This bolt is commonly used in structural steel connections, bridge construction, heavy equipment mounting, and commercial building frameworks where ASTM A325 compliance is specified by engineers or building codes. The hot-dipped galvanized coating provides corrosion protection in outdoor, wet, or chemically exposed environments. Partial threading preserves shank integrity in the bearing zone of bolted joints, which is a standard requirement in structural steel design per AISC and RCSC specifications.

Key Features

• ASTM A325 certified high-strength structural bolt
• 1-8 UNC thread size with partial threading for shank bearing zone integrity
• 7.5 inches length under head for deep structural connections
• Hot-dipped galvanized finish for corrosion resistance in exposed environments
• A325-grade steel construction for high tensile and proof load capacity
• Inch measurement system, compatible with standard imperial fastener hardware

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use in imperial-standard bolted steel connections requiring 1-8 UNC threading and 7.5-inch under-head length.

Installation Notes

Installation should be performed by qualified ironworkers or structural contractors in accordance with RCSC Specification for Structural Joints and applicable building codes. Power down or de-energize any adjacent systems before working in proximity to electrical infrastructure. Use calibrated torque wrenches or tension-control methods as required by the structural engineer of record. Do not reuse bolts that have been fully tensioned unless approved by the engineer of record.
