Value Collection HCI40750375N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI40750375N-005BX is a 3/4-10 hex head bolt rated to ASTM A490 structural steel standards. It features a 3-3/4 inch length under head with partial threading and an uncoated, bright finish. The A490 designation identifies this bolt as a high-strength structural fastener manufactured from alloy steel, suited for heavy-duty bolted connections. It is installed by ironworkers, structural steel contractors, and commercial millwrights in applications requiring verified tensile performance under load. The UNC thread form and hex head drive make it compatible with standard impact and torque tooling found on most job sites.

This bolt is used in structural steel assemblies, steel-to-steel connections, and heavy equipment mounting applications where ASTM A490 compliance is specified by the engineer of record. It is appropriate for both new construction and retrofit applications in commercial and industrial settings where high-strength fasteners are required by specification. Partial threading provides a defined grip length for load-bearing joints where the unthreaded shank must occupy the shear plane.

Key Features

• ASTM A490 high-strength structural bolt standard
• Thread size 3/4-10 UNC for compatibility with standard structural hardware
• 3-3/4 inch length under head for thick-section connections
• Partially threaded shank preserves grip length through the shear plane
• Bright uncoated finish — no coating thickness to account for in hole tolerancing
• Inch system of measurement throughout

Compatibility

Designed as an OEM-style replacement or new-installation fastener for structural steel bolted connections requiring ASTM A490 high-strength hex head bolts in 3/4-10 UNC thread size.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or structural steel installers following AISC and RCSC specifications for high-strength bolted connections. Power down or de-energize any adjacent electrical equipment before working in the connection area. Do not substitute A490 bolts where A325 is specified, or vice versa, without engineer approval. Torque or tension values must be sourced from the project structural drawings or the RCSC Specification for Structural Joints — do not apply generic torque estimates to structural high-strength bolts.
