Value Collection HCI40870400N-005BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI40870400N-005BX is a partially threaded hex head bolt designed for structural and heavy-duty fastening applications. It features a 7/8-9 UNC thread size and a 4-inch length under head, manufactured from uncoated steel to the ASTM A490 structural bolt standard. Grade A490 fasteners are specified for high-strength structural steel connections and are commonly used where load-bearing performance is critical. This bolt ships individually and is suited for installation by ironworkers, structural fabricators, and contractors working on steel-to-steel connections governed by applicable structural codes.

This bolt is appropriate for structural steel assemblies in both commercial and industrial construction environments. ASTM A490 bolts are typically specified in steel frame construction, bridge work, and heavy equipment fabrication where high-strength fasteners are required by design specifications. Partial threading is standard for most structural bolt applications, where the shank bears shear load and threads engage the nut within the grip length.

Key Features

• 7/8-9 UNC thread size for compatibility with standard structural hex nuts and heavy hex nuts
• 4-inch length under head suits typical structural connection grip lengths
• Partial threading preserves a smooth shank for shear-bearing connections
• ASTM A490 grade steel meets high-strength structural bolt requirements
• Bright uncoated finish — no coating thickness to affect dimensional tolerances
• Inch measurement system — fits standard imperial fastener tooling and inspection gauges

Compatibility

Designed as an ASTM A490-compliant structural hex head bolt for use in high-strength steel connections requiring 7/8-9 UNC threaded fasteners.

Installation Notes

Installation of ASTM A490 structural bolts should be performed by qualified ironworkers or structural mechanics in accordance with AISC and RCSC specification requirements. Verify that the nut, washer, and bolt assembly are all rated to the same structural grade before tensioning. Power down any adjacent energized equipment before working in proximity to electrical infrastructure. Do not substitute A490 bolts with lower-grade fasteners in any connection designed to ASTM A490 specifications.
