Value Collection B7SN1130625UP Threaded Stud Nut 1-1/8-8

Product Description

The VALUE COLLECTION B7SN1130625UP is a fully threaded stud with nut in Grade B7 alloy steel, sized at 1-1/8-8 thread with a 6.25-inch length. Designed for high-strength bolted connections, this stud delivers the tensile strength and temperature resistance that Grade B7 material is known for in pressure vessel, flange, and heavy industrial fastening applications. The 7B thread fit class ensures reliable engagement with compatible nuts. Each package includes four studs and eight nuts, providing matched hardware for immediate installation. The uncoated finish suits applications where post-installation treatment or plating is specified by the project.

This stud and nut set is suited for industrial and mechanical assembly work including pipe flange connections, pressure vessel closures, structural bolting, and equipment mounting. The coarse 1-1/8-8 thread profile is standard for heavy-duty fastening in environments subject to vibration, thermal cycling, or elevated stress loads. Machinists, pipefitters, millwrights, and industrial maintenance technicians are the primary installers of this hardware type.

Key Features

• Grade B7 alloy steel construction provides high tensile strength and elevated-temperature performance
• 1-1/8-8 thread size with 7B class of fit for consistent thread engagement
• 6.25-inch length accommodates standard flange and structural bolting applications
• Uncoated finish allows field-applied coatings or use in dry, controlled environments
• Package includes four studs and eight nuts for matched, ready-to-install hardware sets

Compatibility

Designed as a standard Grade B7 fully threaded stud for use in industrial bolting applications requiring 1-1/8-8 thread size and 7B class of fit.

Installation Notes

Installation should be performed by qualified pipefitters, millwrights, or mechanical technicians familiar with bolted flange and structural fastening procedures. Always de-energize, depressurize, and isolate the system before performing fastener replacement or installation. Follow applicable ASME, ANSI, or plant-specific torque and tensioning procedures for Grade B7 stud bolts. Inspect threads for damage before installation and apply appropriate lubricant or anti-seize compound as required by the application specification.
