Value Collection HCI30870600N-001BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI30870600N-001BX is a 7/8-9 hex head bolt designed for structural and industrial fastening applications. It is manufactured from steel to ASTM A325 specifications, making it suitable for high-strength structural connections. The bolt measures 6 inches in length under the head and features partial threading along the shank, which provides a bearing surface through the grip area of the joint. The uncoated, bright finish is standard for structural applications where additional plating is not required. At approximately 1 pound, this single-unit fastener is suited for heavy-duty assemblies where A325-grade material is specified by design or code.

This bolt is used in structural steel construction, heavy equipment fabrication, and industrial assembly work where ASTM A325 high-strength fasteners are required by specification. Partial threading is common in structural bolted connections where the unthreaded shank spans the material being joined, reducing the risk of thread engagement within the shear plane. It is installed by ironworkers, millwrights, and structural contractors working to AISC or similar structural connection standards. The 7/8-9 UNC thread size is a common designation in North American structural and heavy industrial fastener applications.

Key Features

• ASTM A325 high-strength structural steel grade
• 7/8-9 UNC thread form for compatibility with standard structural hardware
• 6 inches length under head for deep-grip or thick-stack connections
• Partially threaded shank keeps threads out of the shear plane in structural joints
• Bright uncoated finish meets standard A325 structural bolt specifications

Compatibility

Designed as an ASTM A325 high-strength hex head bolt for use with standard 7/8-9 UNC nuts and heavy hex structural hardware in structural steel and industrial fastening assemblies.

Installation Notes

Installation of structural A325 bolts should be performed by qualified trades following AISC structural bolt installation procedures, including snug-tightening and any required pretensioning method such as turn-of-nut or direct tension indicator. Always verify thread engagement and confirm the unthreaded shank is positioned correctly within the grip before final tightening. Do not use impact tools without confirming they are calibrated for A325 pretension requirements. Follow applicable project structural specifications and local codes.
