Value Collection HCI40870375N-005BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI40870375N-005BX is a hex head structural bolt used in heavy-duty bolted connections that require high-strength fastening. It carries an A490 material grade and conforms to ASTM A490, making it appropriate for structural steel construction applications where load-bearing integrity is critical. The bolt measures 3-3/4 inches in length under the head with a 7/8-9 UNC thread size and is partially threaded, meaning the shank provides a bearing surface in the grip zone while the threaded portion engages the nut. It ships uncoated with a bright finish and weighs 1.161 pounds.

This bolt is used in structural steel connections, moment frames, and high-strength bolted assemblies commonly found in commercial and industrial construction. It is installed by ironworkers, structural steel erectors, and contractors working on projects governed by AISC and RCSC specifications. The 7/8-9 UNC thread pattern is a standard sizing used widely across structural connection hardware, and the partially threaded shank suits applications where shear load transfer through the bolt body is required.

Key Features

• ASTM A490 certified high-strength structural bolt
• 7/8-9 UNC thread size with partial threading for shear-critical connections
• 3-3/4 inch length under head accommodates standard structural grip lengths
• Uncoated bright finish suitable for use with standard structural washers and heavy hex nuts
• Inch system of measurement for compatibility with imperial-dimensioned structural hardware

Compatibility

Designed as an OEM-style replacement and standard-supply structural bolt for high-strength bolted connections requiring ASTM A490 compliance in imperial fastener sizing.

Installation Notes

Installation of ASTM A490 structural bolts must be performed by qualified ironworkers or structural contractors in accordance with RCSC Specification for Structural Joints Using High-Strength Bolts. Power down or de-energize any adjacent systems before working in proximity to live electrical infrastructure on structural projects. Do not reuse A490 bolts that have been fully tensioned, as they are not rated for reuse under RCSC guidelines. Follow the applicable torque or tension control method specified in the project drawings and structural specifications.
