Value Collection HCI31120650N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31120650N-005BX is a heavy hex head bolt engineered for structural and industrial fastening applications. This bolt features a 1-1/8-7 UNC thread size with a 6-1/2 inch length under head, manufactured from steel to ASTM A325 material grade requirements. The partially threaded shank provides a smooth bearing surface along the grip length, which is essential for high-strength structural connections. It ships in an uncoated, bright finish. Licensed contractors, ironworkers, and millwrights typically specify this fastener in heavy structural assemblies where ASTM A325 compliance is required.

This bolt is used in heavy structural steel construction, equipment mounting, and industrial framework applications where high-strength fasteners meeting ASTM A325 standards are specified. The 1-1/8-7 UNC thread pitch and partial threading configuration make it well suited for thick-flange and heavy-plate connections common in commercial and industrial construction. Installation typically follows engineer-specified torque requirements and project structural drawings.

Key Features

• ASTM A325 grade steel construction for high-strength structural applications
• 1-1/8-7 UNC thread size with 6-1/2 inch length under head
• Partially threaded shank provides full bearing surface along grip length
• Bright uncoated finish suitable for field painting or coating as specified
• Inch measurement system for compatibility with standard structural fastener specifications

Compatibility

Designed as an ASTM A325 high-strength structural hex head bolt for use in heavy steel construction and industrial fastening applications where A325-grade fasteners are required by specification.

Installation Notes

Installation of structural A325 bolts should be performed by qualified ironworkers or structural mechanics following applicable project specifications and the AISC or RCSC Specification for Structural Joints Using High-Strength Bolts. Power down or de-energize any adjacent systems before working in close proximity to electrical equipment. Use calibrated torque wrenches or tension-control methods as required by the structural engineer of record. Do not substitute uncoated fasteners in environments requiring corrosion-resistant finishes without engineering approval.
