Value Collection B7SN1130675UP Threaded Stud Nut 1-1/8-8

Product Description

The VALUE COLLECTION B7SN1130675UP is a fully threaded stud with nuts designed for heavy-duty fastening applications. Made from Grade B7 alloy steel, this stud meets ASTM A193 standards, making it suitable for high-strength bolting in structural, pressure vessel, and industrial piping applications. The stud measures 6.75 inches in length with a 1-1/8-8 thread size and a 7B class of fit, providing secure, precise thread engagement. Each package includes 4 studs and 8 nuts, offering a complete fastening assembly. The uncoated finish makes it well suited for applications where additional coating or plating will be applied in the field.

This stud and nut assembly is used in industrial and commercial settings where high-tensile, heat-resistant fasteners are required. Typical applications include flanged pipe connections, pressure vessels, heat exchangers, and structural steel assemblies. The ASTM A193 Grade B7 designation is a recognized standard for high-strength alloy steel bolting material commonly specified in petrochemical, power generation, and heavy mechanical installations. Maintenance mechanics, pipefitters, and structural ironworkers typically install this hardware.

Installation Notes

Installation of Grade B7 studs and nuts is typically performed by licensed pipefitters, millwrights, or structural mechanics. Always de-energize and depressurize the system before disassembling flanged connections or structural joints. Follow applicable codes including ASME B31.3 for process piping or relevant structural steel standards when specifying torque and preload values. Inspect threads for damage before installation and apply thread lubricant or anti-seize compound as required by the application specification.
