Value Collection B7SN0630400CP Threaded Stud Nut 5/8-11 4in

Product Description

The VALUE COLLECTION B7SN0630400CP is a fully threaded stud and nut set built to ASTM A193 Grade B7 standards. Each stud is 4 inches long with a 5/8-11 thread size and a 7B class of fit, making it suitable for high-strength bolting applications where consistent clamping force and thread engagement are critical. Constructed from alloy steel with an uncoated finish, these studs deliver reliable mechanical performance in industrial and structural fastening work. Each package includes four studs and eight nuts, providing complete hardware for multiple fastening points. The Grade B7 designation indicates high tensile strength alloy steel, commonly specified in pressure vessel, flange, and pipe fitting assemblies.

These threaded studs are used in industrial piping, flanged connections, pressure vessel assembly, and structural bolting applications. They are appropriate for both shop fabrication and field installation where ASTM A193 Grade B7 fasteners are called out in engineering specifications. Typical users include pipefitters, millwrights, mechanical contractors, and industrial maintenance technicians. The 7B thread fit class provides a standard allowance for external threads, ensuring consistent fit with mating nuts across standard tooling.

Key Features

• ASTM A193 Grade B7 alloy steel construction for high-strength bolting service
• 5/8-11 thread size with 7B class of fit for reliable thread engagement
• 4 inches overall length, fully threaded along the entire shank
• Uncoated finish — suitable for service environments where coatings are not required or where field coating will be applied
• Packaged with four studs and eight nuts per package for complete installation hardware

Compatibility

Designed as a standard ASTM A193 Grade B7 threaded stud for use in flanged piping, pressure vessel, and structural bolting applications that specify 5/8-11 fully threaded studs.

Installation Notes

Installation is typically performed by pipefitters or mechanical contractors following applicable ASME or plant-specific torque specifications for Grade B7 fastener assemblies. Power down or depressurize any system before removing or replacing flange fasteners. Use calibrated torque tools and follow the applicable code or engineering specification for the joint being assembled. Do not substitute these fasteners in applications requiring a different material grade or finish without verifying engineering approval.
