Value Collection B7SN0880400CP Threaded Stud Nut 7/8-9 4in

Product Description

The VALUE COLLECTION B7SN0880400CP is a fully threaded stud and nut assembly designed for high-strength bolted connections in industrial and mechanical applications. Each package includes four Grade B7 alloy steel studs at 4 inches in overall length with a 7/8-9 thread size, along with eight matching nuts. The Grade B7 designation meets ASTM A193 standards, confirming the material is suited for elevated-temperature and high-pressure service. The uncoated finish means the steel is bare and ready for field-applied coatings or use in environments where coating is not required. Machinists, maintenance technicians, and pipefitters commonly work with this type of hardware.

This stud and nut assembly is used in flanged pipe connections, pressure vessel closures, structural bolting, and heavy equipment maintenance across industrial, commercial, and process-industry settings. The 7B thread fit class indicates a loose-fit external thread, which is standard for stud bolting applications where ease of assembly and field installation are priorities. Typical applications include bolting pipe flanges in process piping systems, securing pressure vessel covers, and general structural assembly work requiring ASTM A193 Grade B7 compliance.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 for high-temperature and high-pressure service
• 7/8-9 thread size with 7B class of fit for standard stud bolting applications
• 4 inches overall length provides consistent grip length for flanged connections
• Uncoated finish suitable for field coating or bare-metal installations
• Package includes four studs and eight nuts for complete assembly
• Fully threaded along the entire shank length for maximum engagement flexibility

Compatibility

Designed as an ASTM A193 Grade B7 compliant stud and nut set for standard 7/8-9 threaded bolting applications in flanged piping, pressure vessel, and structural assembly work.

Installation Notes

Installation is performed by pipefitters, millwrights, or maintenance mechanics familiar with ASTM A193 bolting requirements. De-energize and depressurize any system before replacing or installing stud bolts in flanged connections. Follow applicable codes such as ASME B16.5 or applicable plant bolting procedures for proper torque sequencing on flanged joints. Do not mix Grade B7 studs with incompatible nut grades in critical pressure applications.
