Value Collection B7SN0880975CP Threaded Stud Nut 7/8-9 Steel

Product Description

The VALUE COLLECTION B7SN0880975CP is a fully threaded stud and nut assembly designed for heavy-duty fastening applications across industrial, mechanical, and trade installations. Each stud is manufactured from steel to Material Grade B7 specification, which indicates high-strength alloy steel suitable for demanding service conditions including elevated temperatures and high-load joints. The thread size is 7/8-9 (7/8 inch diameter, 9 threads per inch) with a 7B Class of Fit, and each stud measures 9-3/4 inches in length. The uncoated finish leaves the base steel exposed, making these studs appropriate where coatings would interfere with fitment or where field treatment is preferred. Each package includes 4 studs and 8 nuts.

These studs are commonly used in flange bolting, pressure vessel assembly, pump mounting, pipe flange connections, and general structural fastening in commercial and industrial settings. The Grade B7 alloy steel construction makes them a standard choice for ASME and ASTM bolting applications where tensile strength requirements exceed those of common carbon steel fasteners. Licensed trades including pipefitters, millwrights, and mechanical contractors regularly specify B7 stud assemblies for high-pressure and high-temperature service points.

Key Features

• Grade B7 alloy steel construction for high-strength, high-temperature service
• 7/8-9 thread size with 7B Class of Fit for consistent engagement tolerances
• 9-3/4 inch stud length for deep flange or structural applications
• Fully threaded along entire stud length for maximum fastening flexibility
• Uncoated finish suitable for field coating or direct installation
• Package includes 4 studs and 8 nuts ready for immediate use

Compatibility

Designed as an OEM-style replacement or direct-installation fastener for industrial and mechanical assemblies requiring 7/8-9 fully threaded B7-grade studs with matching nuts.

Installation Notes

Installation of B7 stud assemblies should be performed by qualified pipefitters, millwrights, or mechanical contractors familiar with applicable ASME, ANSI, or ASTM bolting standards. Always de-energize, depressurize, and isolate the system before removing or installing flange fasteners. Use calibrated torque tools to achieve proper clamp load — refer to the applicable flange or equipment specification for torque values, as none are provided here. Inspect threads for damage before installation and verify nut engagement meets job specification requirements.
