Value Collection HCI41120550N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI41120550N-005BX is a heavy hex head bolt designed for structural and high-strength fastening applications. It features a 1-1/8-7 UNC thread size with a 5-1/2 inch length under head and is partially threaded. Manufactured from steel to ASTM A490 specifications, this bolt meets the material and mechanical requirements for high-strength structural bolts used in steel construction. The uncoated finish maintains dimensional precision and is appropriate for applications where coatings are not required or where field treatment will be applied. At 2.447 pounds, this is a substantial fastener suited for heavy structural connections.

This bolt is used in structural steel construction, heavy industrial assemblies, and high-load bearing connections where ASTM A490 compliance is required. Typical installations include steel-to-steel connections in commercial and industrial building frameworks, bridges, and other engineered structures. It is installed by ironworkers, structural steel erectors, and millwrights operating under engineering specifications that call out A490-grade fastener sets. Partial threading is common in bearing-type connections where the bolt shank occupies the shear plane.

Key Features

• 1-1/8-7 UNC thread size for heavy structural fastener applications
• 5-1/2 inch length under head, partially threaded
• Uncoated bright finish for precise dimensional tolerancing
• Steel construction meeting A490 material grade requirements
• Inch system of measurement throughout

Compatibility

Designed as an OEM-style replacement or direct-use structural fastener for applications specifying ASTM A490 high-strength hex head bolts with a 1-1/8-7 UNC thread and 5-1/2 inch under-head length.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or structural mechanics following applicable AISC and RCSC specifications for high-strength bolting. Before installation, verify that the bolt assembly includes the required nuts and washers as specified by the connection design. Never reuse A490 bolts that have been fully tensioned, as high-strength structural bolts are not rated for reuse. Torque or tension values must be derived from the project engineering specifications and applicable standards — do not install to generic torque tables.
