Value Collection B7SN1130600UP Threaded Stud Nut 1-1/8-8 6in B7

Product Description

The VALUE COLLECTION B7SN1130600UP is a fully threaded stud and nut assembly manufactured from ASTM A193 Grade B7 alloy steel. Each stud measures 1-1/8-8 thread size and 6 inches in overall length, supplied in an uncoated finish. The Grade B7 designation indicates a high-strength, heat-treated chromium-molybdenum steel construction commonly specified for high-temperature and high-pressure bolting applications. This package includes 4 studs and 8 nuts, with a 7B class of fit for controlled thread engagement. Licensed trades and industrial maintenance professionals use these assemblies in flanged pipe connections, pressure vessel work, and structural bolting where elevated tensile strength and ASTM compliance are required.

These stud and nut assemblies are suited for industrial piping systems, pressure equipment, and mechanical connections operating under elevated temperature and pressure conditions. The ASTM A193 standard governs alloy steel bolting used in high-temperature or high-pressure service, making this hardware appropriate for refineries, chemical plants, power generation facilities, and commercial HVAC or plumbing applications that require code-compliant fasteners. The 1-1/8-8 coarse thread pitch is a standard configuration for heavy-duty flange bolting across these service environments.

Key Features

• Grade B7 alloy steel construction meeting ASTM A193 requirements for high-temperature and high-pressure bolting
• 1-1/8-8 thread size with 7B class of fit for precise thread engagement and load distribution
• 6-inch overall length suits standard heavy-duty flange and structural bolting configurations
• Uncoated finish — suitable for environments where coating would interfere with torque values or dimensional tolerances
• Package includes 4 studs and 8 nuts for complete fastening assemblies
• UNSPSC Code 31163300 for procurement and catalog classification

Compatibility

Designed as an ASTM A193 Grade B7 compliant threaded stud assembly for flanged piping, pressure vessel connections, and heavy-duty mechanical bolting applications requiring 1-1/8-8 thread size and 6-inch length fasteners.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or licensed mechanic familiar with ASME or ASTM bolting standards. De-energize, depressurize, and isolate the system fully before replacing any flange or pressure vessel fasteners. Verify thread class compatibility between studs and mating components before assembly. Consult applicable codes such as ASME B31.3 or ASME Boiler and Pressure Vessel Code for torque sequencing and inspection requirements specific to the installation.
