Value Collection HCI31250750NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31250750NG-005BX is a heavy-duty hex head bolt designed for structural and industrial fastening applications. It features a 1-1/4-7 UNC thread size with a 7-1/2-inch length under head and partial threading. Manufactured from steel to ASTM A325 Grade A325 specifications, this bolt carries a hot-dipped galvanized finish for corrosion resistance in exposed or harsh environments. It is suited for use in steel-to-steel connections, heavy equipment mounting, and structural assemblies where high-strength fasteners meeting recognized industry standards are required.

This bolt is appropriate for use in commercial and industrial construction, structural steel fabrication, and heavy mechanical assemblies. Typical install scenarios include steel frame connections, bridge and infrastructure components, and heavy machinery mounting points where ASTM A325 structural bolt requirements apply. The hot-dipped galvanized finish makes it a practical choice for outdoor or moisture-prone installations where bare steel fasteners would be inadequate.

Key Features

• ASTM A325 Grade A325 structural bolt standard for verified high-strength performance
• 1-1/4-7 UNC thread size with partial threading along shank
• 7-1/2-inch length under head for deep structural connections
• Hot-dipped galvanized finish provides durable corrosion resistance
• Steel construction rated to A325 material grade requirements
• Inch measurement system; package quantity of 1

Compatibility

Designed as an OEM-style structural fastener for applications requiring ASTM A325 compliant hex head bolts in 1-1/4-7 UNC thread size with a 7-1/2-inch length under head.

Installation Notes

Installation of structural A325 bolts should be performed by qualified ironworkers, millwrights, or structural mechanics in accordance with AISC and applicable building codes. Power down or de-energize any adjacent systems before working in live structural or electrical environments. Use calibrated torque wrenches or tension-control methods as specified by the project engineer. Do not reuse structural bolts once fully tensioned unless specifically permitted by the project specification.
