Value Collection B7SN1250750UP Threaded Stud Nut 1-1/4-8 Steel 4pk

Product Description

The VALUE COLLECTION B7SN1250750UP is a fully threaded stud and nut assembly used in heavy-duty fastening applications across mechanical, plumbing, and industrial piping systems. Each stud measures 7.5 inches in length with a 1-1/4-8 thread size and a 7B class of fit, offering consistent engagement and reliable clamping force. Manufactured from Grade B7 alloy steel in an uncoated finish, these studs deliver high tensile strength suitable for demanding bolted connections such as flanged joints, pressure vessel closures, and structural assemblies. Each package contains 4 studs and 8 nuts, providing complete hardware for multiple connection points.

These studs are commonly used in industrial piping flange assemblies, pressure equipment, and structural bolting applications where high-strength, full-thread engagement is required. Grade B7 alloy steel is a standard specification for high-temperature and high-pressure service, making this hardware appropriate for mechanical rooms, boiler connections, and process piping installations in both commercial and industrial settings. Licensed plumbers, pipefitters, and millwrights regularly specify Grade B7 threaded stud assemblies for flanged pipe joint applications governed by ASME and ANSI standards.

Key Features

• Grade B7 alloy steel construction for high tensile strength and temperature resistance
• 1-1/4-8 thread size with 7B class of fit for controlled thread engagement
• Full-thread stud design provides maximum engagement length across the entire 7.5-inch body
• Uncoated finish suitable for environments where coating compatibility or field treatment is required
• Each package includes 4 studs and 8 nuts for complete assembly hardware
• UNSPSC Code 31163300 for streamlined procurement and catalog classification

Compatibility

Designed as a standard Grade B7 fully threaded stud assembly suitable for flanged joint connections, pressure vessel bolting, and industrial piping applications requiring 1-1/4-8 thread sizing.

Installation Notes

Installation should be performed by qualified pipefitters, plumbers, or mechanical contractors following applicable ASME, ANSI, or facility-specific torque and assembly procedures. De-energize and depressurize the system fully before disassembling any flanged connection. Use appropriate hand tools and thread lubricant as specified by the applicable flange standard. Inspect stud and nut threads for damage before assembly to ensure proper class of fit is maintained.
