Value Collection HCI41000225N-005BX Hex Head Bolt Steel A490

Product Description

The VALUE COLLECTION HCI41000225N-005BX is a fully threaded hex head bolt manufactured from steel to ASTM A490 structural bolt standards. It features a 1-8 UNC thread size and a 2-1/4 inch length under head, with an uncoated bright finish. This bolt is designed for high-strength structural connections where ASTM A490 compliance is specified. Installation is performed by ironworkers, structural steel erectors, and millwrights working to engineered connection drawings. The A490 designation indicates a quenched-and-tempered alloy steel bolt rated for heavy structural applications.

This bolt is suited for structural steel fabrication, heavy equipment assembly, bridge construction, and industrial framing applications where high-strength fasteners meeting ASTM A490 specifications are required. The fully threaded configuration allows engagement along the entire shank length, providing flexibility in connection depth without a grip-length limitation from a partial thread. It is sold individually and is appropriate for both shop fabrication and field erection work.

Key Features

• ASTM A490 certified high-strength structural bolt
• Fully threaded shank for maximum thread engagement flexibility
• 1-8 UNC thread form for compatibility with standard heavy-hex nuts
• 2-1/4 inch length under head for precise structural fit-up
• Bright uncoated finish suitable for painted or galvanized connection assemblies
• Steel construction with quenched-and-tempered material grade

Compatibility

Designed for use in structural steel connections requiring ASTM A490 high-strength bolting assemblies, typically paired with A563 heavy-hex nuts and F436 hardened washers per AISC and RCSC bolting specifications.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or structural steel erectors following RCSC Specification for Structural Joints requirements. Always snug-tighten the bolt assembly before applying final pretension using the turn-of-nut, tension control, or direct tension indicator method as specified in the project drawings. Power down or de-energize any adjacent electrical equipment before working in proximity to structural steel under load. Do not reuse A490 bolts once fully tensioned, as retightening is not permitted under RCSC standards.
