Value Collection B7SN0880750CP Threaded Stud Nut 7/8-9

Product Description

The VALUE COLLECTION B7SN0880750CP is a fully threaded stud and nut assembly used in high-strength bolted connections across industrial, mechanical, and structural applications. Each stud measures 7/8-9 thread size and 7.5 inches in length, manufactured from alloy steel to ASTM A193 Grade B7 material standards. The uncoated finish is standard for applications where coatings are applied on-site or where bare alloy steel meets the service requirement. This package includes four studs and eight nuts, providing complete fastener sets for multiple connection points in a single order. Maintenance mechanics, pipefitters, and millwrights typically source these for flange bolting, pressure vessel assembly, and structural bolted joints.

Grade B7 alloy steel studs are widely used in flanged pipe connections, heat exchangers, pressure vessels, and heavy industrial equipment. The 7B class of fit designation indicates a standard clearance thread fit appropriate for general industrial bolting where parts must assemble freely under typical field conditions. The 7/8-9 thread size is a common Unified National Coarse (UNC) designation suited to medium and heavy-duty structural and mechanical assemblies in both shop fabrication and field installation environments.

Key Features

• ASTM A193 Grade B7 alloy steel construction for high-strength bolting service
• 7/8-9 UNC thread size, 7.5 inches long, fully threaded
• 7B thread fit class for standard clearance and free assembly
• Uncoated finish suitable for site-applied coatings or bare-alloy service
• Package includes four studs and eight nuts for complete fastener sets

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial flanged assemblies, pressure vessel connections, and structural bolted joints requiring ASTM A193 Grade B7 alloy steel studs in 7/8-9 thread size.

Installation Notes

Installation is typically performed by licensed pipefitters, millwrights, or maintenance mechanics following applicable ASME, ASTM, or facility torque and bolting procedures. Always de-energize, depressurize, and lock out the system before servicing any flanged or pressure-bearing connection. Use calibrated torque tools and follow the applicable bolting sequence specified by the system design engineer or applicable code. Do not substitute Grade B7 studs in applications requiring different material grades without engineering review.
