Value Collection HCI41000350N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI41000350N-005BX is a heavy-structural hex head bolt engineered to ASTM A490 standards. It features a 1-8 UNC thread and measures 3-1/2 inches in length under the head. Manufactured from uncoated steel at the A490 material grade, this bolt is partially threaded and sized for high-strength structural connections. It is intended for installation by ironworkers, structural steel erectors, and general contractors working on steel-to-steel connections where high-strength fasteners are specified by the engineer of record. The bright, uncoated finish is standard for A490 structural bolts used in typical dry or painted structural applications.

This bolt is suited for high-strength structural steel connections in commercial, industrial, and infrastructure construction. ASTM A490 bolts are commonly specified in steel moment frames, column splices, beam-to-column connections, and other structural assemblies governed by AISC and RCSC bolt specifications. Partially threaded shanks are used where the shank must occupy the shear plane of the joint. This item ships in a package quantity of 1 bolt per unit.

Key Features

• ASTM A490 certified high-strength structural bolt
• 1-8 UNC thread form for standard inch-series structural connections
• 3-1/2 inch length under head, partially threaded shank
• Uncoated bright finish — no additional coating to interfere with pretension values
• Steel construction at A490 material grade for heavy structural load requirements

Compatibility

Designed as a direct-fit ASTM A490 structural hex bolt for high-strength steel connections requiring 1-8 UNC thread and 3-1/2 inch grip-range fasteners per AISC and RCSC specifications.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or structural steel erectors in accordance with RCSC Specification for Structural Joints. The joint and mating surfaces should be inspected and cleaned before fastener installation. Use calibrated torque wrenches or tension-control tooling appropriate for A490 fasteners to achieve required pretension. Never reuse A490 bolts once fully tensioned, as the material may have yielded.
