Value Collection HCI41000300N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI41000300N-005BX is a heavy-hex structural bolt designed for high-strength bolted connections in steel construction and heavy fabrication. It carries an ASTM A490 material grade, which qualifies it for structural steel joints governed by AISC and RCSC specifications. The bolt is partially threaded with a 1-8 UNC thread pattern and measures 3 inches under the head. The bright, uncoated finish makes it suitable for dry or controlled-environment installations where surface treatment is specified separately by the engineer of record. Structural ironworkers, steel erectors, and commercial contractors are the primary installers of this fastener type.

This bolt is used in heavy structural steel applications including moment frames, column base plates, beam-to-column connections, and braced frames in commercial and industrial construction. The ASTM A490 designation indicates a quenched-and-tempered alloy steel fastener with minimum tensile strength significantly higher than standard Grade 5 or Grade 8 hardware. It is sold individually and is appropriate where job-site control of fastener grade and traceability is required by the structural drawings or inspection protocol.

Key Features

• ASTM A490 grade alloy steel construction for high-strength structural bolting
• 1-8 UNC thread standard for compatibility with standard structural nut and washer sets
• 3-inch length measured under the head for precise grip-length selection
• Partially threaded shank to maximize shear capacity in the bearing zone
• Bright uncoated finish — no additional coating to affect dimensional tolerances
• Sold as single unit for controlled, quantity-specific procurement

Compatibility

Designed for use in structural steel bolted connections requiring ASTM A490 high-strength fasteners per RCSC Specification for Structural Joints, typically paired with heavy hex nuts and hardened washers of matching specification.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or steel erectors in accordance with the RCSC Specification for Structural Joints and applicable building code requirements. Bolt assemblies should be inspected for grade markings and stored to prevent contamination before installation. Pre-installation verification of rotational capacity is required when specified by the structural engineer. Do not substitute A490 bolts with lower-grade hardware, and do not apply paint, lubricants, or coatings not specified by the engineer of record, as these can affect pretension values.
