Value Collection B7SN0880725CP Threaded Stud Nut 7/8-9 Steel

Product Description

The VALUE COLLECTION B7SN0880725CP is a fully threaded stud and nut set designed for high-strength fastening in industrial and mechanical applications. Each stud measures 7-1/4 inches in length with a 7/8-9 thread size and is manufactured from Grade B7 alloy steel, which provides the tensile strength needed for heavy bolting work. The uncoated finish is standard for applications where additional coatings are applied in the field or where bare steel is specified. Each package contains four studs and eight nuts. This hardware is installed by millwrights, pipefitters, and mechanical contractors in structural and pressure-boundary assemblies.

These Grade B7 threaded studs are suited for use in flanged pipe connections, pressure vessel assemblies, structural steel fabrication, and general industrial machinery. The 7B thread fit class indicates a looser tolerance fit standard for plated or coated assemblies or where ease of assembly under field conditions is required. The 7/8-9 coarse thread series is a common specification in heavy-duty bolting across petrochemical, power generation, and manufacturing environments.

Key Features

• Grade B7 alloy steel construction for high tensile strength and durability
• 7/8-9 coarse thread series with 7B class of fit for field assembly compatibility
• Fully threaded along the entire 7-1/4 inch length for maximum engagement flexibility
• Uncoated finish suitable for field coating, plating, or bare-steel installations
• Each package includes four studs and eight nuts for complete fastener sets

Compatibility

Designed as a standard Grade B7 fully threaded stud for use in flanged connections, pressure vessel bolting, and industrial mechanical assemblies requiring 7/8-9 coarse thread fasteners.

Installation Notes

Installation is performed by qualified millwrights, pipefitters, or mechanical contractors following applicable codes such as ASME B16.5 for flanged connections or relevant structural standards. De-energize and depressurize any system before replacing fasteners in live assemblies. Use calibrated torque tools to achieve required bolt load; refer to the applicable engineering specification or flange standard for target torque values. Inspect threads for damage before installation and ensure nuts run freely by hand before applying torque.
