Value Collection HCI41120325N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI41120325N-005BX is a fully threaded hex head bolt designed for structural and heavy-duty fastening applications. It features a 1-1/8-7 UNC thread with a 3-1/4 inch length under head, manufactured from steel to the ASTM A490 specification. The uncoated bright finish is standard for high-strength structural bolts used in steel-to-steel connections. This bolt is installed by ironworkers, structural steel erectors, and mechanical contractors working on commercial and industrial assemblies where high-strength fasteners are specified by engineers.

This bolt is suited for structural steel connections in commercial construction, bridge work, and heavy industrial equipment assembly where ASTM A490 high-strength fasteners are required by design specification. The fully threaded configuration provides thread engagement along the entire shank, making it appropriate for applications where full thread contact through the joined material is needed. Licensed contractors and structural ironworkers are the typical installers on projects governed by AISC and related structural codes.

Key Features

• ASTM A490 high-strength structural steel bolt specification
• 1-1/8-7 UNC thread — coarse thread series for reliable engagement in structural applications
• 3-1/4 inch length under head for appropriate grip range
• Fully threaded shank provides maximum thread engagement through the full fastener length
• Bright uncoated finish — standard for A490 structural bolts per specification requirements
• Inch measurement system, compatible with standard SAE tooling

Compatibility

Designed as an OEM-style replacement or new-installation structural hex head bolt for steel-to-steel connections requiring ASTM A490 high-strength fasteners with 1-1/8-7 UNC thread and 3-1/4 inch under-head length.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or structural steel erectors in accordance with AISC and applicable building code requirements. Power down or de-energize any adjacent electrical systems before working in the installation area. Use calibrated torque wrenches or tension-control tools as required by the project specification — do not substitute standard hex bolts where A490 fasteners are explicitly called out. Inspect threads and mating surfaces for damage before installation.
