Value Collection HCI41120450N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI41120450N-005BX is a heavy structural hex head bolt designed for high-strength bolted connections in steel construction and heavy fabrication. Manufactured to ASTM A490 standards, this bolt features a 1-1/8-7 UNC thread size with a 4-1/2 inch length under head. The partially threaded shank provides a bearing surface suited for structural joint applications. The bright, uncoated finish indicates this fastener is intended for use as-received without an applied protective coating. Weighing approximately 2.296 pounds per unit, this is a substantial fastener for demanding load-bearing assemblies. Installation is performed by structural ironworkers, steel erectors, and mechanical contractors working to AISC and RCSC specifications.

This bolt is used in structural steel connections where high-strength fasteners are required, including beam-to-column connections, splice plates, and heavy equipment mounting. ASTM A490 bolts are rated for high-strength structural applications and are commonly specified in commercial construction, industrial fabrication, and bridge work. The partial threading on this fastener is standard practice for structural bolting, ensuring the thread does not pass through the shear plane of the connection.

Compatibility

Designed as an OEM-style replacement or direct-use structural fastener for high-strength bolted steel connections requiring ASTM A490 specification compliance and a 1-1/8-7 UNC thread form.

Installation Notes

ASTM A490 structural bolts must be installed by qualified ironworkers or structural mechanics following RCSC Specification for Structural Joints and applicable building codes. Always power down or de-energize any adjacent systems before working in proximity to energized equipment. Proper installation requires calibrated torque wrenches or tension-control tooling per the specified tightening method — do not estimate tension by feel. Never reuse ASTM A490 bolts once fully tensioned, as they may not be retensioned or reinstalled per RCSC guidelines.
