Value Collection B7SN1130575UP Threaded Stud Nut Grade B7

Product Description

The VALUE COLLECTION B7SN1130575UP is a fully threaded stud and nut set manufactured from Grade B7 alloy steel with an uncoated finish. Each stud measures 1-1/8 - 8 thread size and 5-3/4 inches in length. The Grade B7 material designation indicates a medium-carbon alloy steel heat-treated to provide high tensile strength and resistance to elevated temperatures, making these studs well suited for demanding bolted joint applications. This package includes four studs and eight nuts, with the nuts conforming to a 7B class of fit for reliable thread engagement. Licensed tradespeople and maintenance mechanics working in industrial, mechanical, or structural fastening applications rely on this type of hardware for secure, repeatable connections.

These fully threaded studs are appropriate for use in industrial piping flanges, pressure vessel assemblies, structural connections, and mechanical equipment mounting where high-strength fastening is required. The 1-1/8 - 8 UNC thread form and Grade B7 rating make this set a common choice in ASME and ANSI flange bolting applications found in commercial and industrial HVAC, plumbing, and process piping systems. The uncoated finish is standard for applications where coatings are specified separately or where bare steel is acceptable per the job specification.

Key Features

• Grade B7 alloy steel construction for high tensile strength and elevated-temperature performance
• 1-1/8 - 8 UNC thread form, fully threaded along the entire 5-3/4 inch length
• 7B class of fit for consistent thread engagement with mating nuts
• Uncoated finish suitable for applications requiring bare steel or field-applied coatings
• Package includes four studs and eight nuts for complete bolted joint assemblies

Compatibility

Designed as a standard Grade B7 fully threaded stud set for use in ASME and ANSI flange bolting, pressure vessel, and structural fastening applications requiring 1-1/8 - 8 UNC thread hardware.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or millwright following applicable ASME, ANSI, or job-specific torque and assembly specifications. Disengage all pressure and de-energize the system before disassembling or replacing flange fasteners. Inspect threads and mating nut threads for damage before installation. Do not mix Grade B7 hardware with lower-grade fasteners in the same bolted joint pattern.
