Value Collection B7SN0880375CP Threaded Stud Nut 7/8-9

Product Description

The VALUE COLLECTION B7SN0880375CP is a fully threaded stud with nuts, manufactured from Grade B7 alloy steel to meet ASTM A193 standards. Each stud measures 7/8-9 thread size at 3-3/4 inches in length and is supplied uncoated with a 7B class of fit. Grade B7 material is widely specified for high-strength bolting in pressure, flange, and structural applications where tensile and yield requirements exceed those of standard fasteners. Each package includes four studs and eight nuts, providing a complete fastening assembly ready for installation by plumbers, pipefitters, and mechanical contractors working on pressure equipment, pipe flanges, and structural connections.

This fully threaded stud and nut set is suited for industrial and commercial applications requiring high-strength, code-compliant fasteners. Typical use cases include pressure vessel flange assemblies, valve bonnet connections, heat exchanger closures, and general structural bolting where ASTM A193 Grade B7 specification is called out by the engineer of record or by applicable piping and pressure codes. The uncoated finish is standard for many field and shop bolting scenarios where coatings are not specified.

Key Features

• Grade B7 alloy steel meets ASTM A193 for high-strength pressure and structural bolting
• 7/8-9 thread size with 7B class of fit for standard inch coarse-thread assemblies
• 3-3/4 inches stud length provides adequate thread engagement for typical flange thicknesses
• Uncoated finish suits applications where bare steel is specified or post-installation coating is applied
• Package includes four studs and eight nuts for complete ready-to-install assemblies

Compatibility

Designed as a high-strength replacement or new-installation fastener for flanged pipe assemblies, pressure vessels, and structural connections specifying ASTM A193 Grade B7 studs in 7/8-9 thread size.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician familiar with pressure bolting procedures. De-energize and depressurize the system fully before removing or installing flange fasteners. Torque fasteners in accordance with the flange manufacturer specifications, applicable ASME or ANSI flange standards, and the project engineer of record requirements. Do not mix Grade B7 studs with non-rated or mismatched nuts in pressure service.
