Value Collection HCI40870275N-005BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI40870275N-005BX is a fully threaded hex head bolt designed for structural and heavy-duty fastening applications. It features a 7/8-9 UNC thread size and a 2-3/4 inch length under head, manufactured from steel to ASTM A490 material grade standards. The uncoated bright finish is standard for high-strength structural bolt applications. This bolt is installed by ironworkers, structural steel contractors, and millwrights in applications where ASTM A490 compliance is specified by the engineer of record.

This bolt is suited for structural steel connections in commercial, industrial, and infrastructure construction where high-strength fasteners meeting ASTM A490 specifications are required. The fully threaded configuration allows engagement along the entire shank length, making it well suited for shorter grip-length connections and applications where thread engagement depth must be maximized. It is sold individually and is appropriate for use wherever a single high-strength hex bolt is needed to complete or repair a bolted connection.

Key Features

• Thread size 7/8-9 UNC, fully threaded along the entire shank
• 2-3/4 inch length under head for precise grip-length control
• Steel construction meeting ASTM A490 high-strength bolt standard
• Bright uncoated finish suitable for dry or protected structural environments
• Inch measurement system; compatible with standard UNC tooling and nuts

Compatibility

Designed as an OEM-style replacement or direct-use fastener for structural steel bolted connections specifying ASTM A490 high-strength hex bolts in 7/8-9 UNC thread size.

Installation Notes

Installation of ASTM A490 structural bolts should be performed by qualified ironworkers or structural steel erectors in accordance with the Research Council on Structural Connections (RCSC) Specification for Structural Joints. Power down or de-energize any adjacent electrical systems before working in the bolt zone. Use calibrated torque wrenches or tension-control tooling as required by the project specification. Do not reuse ASTM A490 bolts once fully tensioned, as they are not rated for re-tensioning after initial installation.
