Value Collection HCI30750475N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI30750475N-005BX is a 3/4-10 hex head bolt designed for structural and heavy-duty fastening applications. Manufactured from steel to ASTM A325 standards, this bolt measures 4-3/4 inches in length under the head and features a partially threaded shank. The uncoated, bright finish leaves the steel in its natural state for applications where surface treatment is applied after installation or where coating is not required. At 0.916 pounds, this is a robust fastener suited for steel-to-steel connections in structural assemblies, construction framing, and mechanical equipment mounting.

This bolt is commonly used in structural steel construction, bridge fabrication, heavy equipment assembly, and industrial fastening where ASTM A325 compliance is specified by engineering drawings or project specifications. The 3/4-10 UNC thread size and partial threading make it well suited for bolted connections requiring a grip length through thick steel plates or multiple members. Installation typically requires a standard hex wrench, impact gun, or torque wrench calibrated to the project engineer's specification.

Key Features

• ASTM A325 structural bolt standard compliance for high-strength steel fastening
• 3/4-10 UNC thread ensures broad compatibility with standard structural hardware
• Partially threaded shank provides a smooth bearing surface through the grip length
• Uncoated bright finish suitable for field coating, galvanizing, or bare structural use
• Steel construction delivers the tensile strength required by A325 specifications

Compatibility

Designed as an OEM-style replacement or new-installation fastener for structural steel assemblies requiring ASTM A325 compliant hex head bolts in the 3/4-10 thread size.

Installation Notes

Installation of structural A325 bolts should be performed by qualified ironworkers, millwrights, or structural mechanics in accordance with applicable codes, including AISC and RCSC specifications for structural joints. Always de-energize or lock out adjacent equipment before performing fastener work on energized machinery. Do not use an impact driver without verifying that the specified torque or tension method is approved for the connection type. Inspect threads and mating nut before installation to ensure clean engagement.
