Value Collection HCI41120375N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI41120375N-005BX is a heavy-duty hex head bolt engineered for structural and industrial fastening applications. It features a 1-1/8-7 UNC thread with a 3-3/4 inch length under head, manufactured from uncoated steel to the ASTM A490 structural bolt standard. Partial threading provides full bearing length along the shank, which is critical in high-load slip-critical and bearing-type structural connections. This bolt is installed by ironworkers, structural erectors, and millwrights working to code-compliant connection specifications. At 2.096 pounds per unit, it is suited for heavy structural assemblies where verified material grade documentation is required.

This bolt is intended for use in structural steel connections governed by ASTM A490 requirements, including high-strength bolted joints in commercial and industrial construction. It is appropriate for use in moment frames, bolted splice plates, and other connections where high-proof-load fasteners are specified by a structural engineer of record. Its bright, uncoated finish is standard for bare steel structural applications and is compatible with typical field inspection and tension-control procedures used on job sites following AISC or RCSC bolt specifications.

Key Features

• ASTM A490 certified high-strength structural bolt for heavy bolted connections
• 1-1/8-7 UNC thread form for compatibility with standard structural nuts and washers
• Partial threading preserves full shank bearing length for shear-critical connections
• Uncoated bright finish meets bare steel job-site inspection requirements
• Inch measurement system with 3-3/4 inch length under head

Compatibility

Designed as an ASTM A490-compliant high-strength structural hex bolt for use with standard 1-1/8 inch heavy hex nuts and hardened washers in structural steel assemblies.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or structural bolting crews following RCSC Specification for Structural Joints and applicable building code requirements. Always power down or de-energize any adjacent systems before working in confined structural bays. Bolts must be installed with appropriate hardened washers under the head and nut as required by the connection design. Do not substitute standard hex nuts for heavy hex nuts specified for A490 assemblies.
