Value Collection B7SN0880650CP Threaded Stud Nut 7/8-9

Product Description

The VALUE COLLECTION B7SN0880650CP is a fully threaded stud and nut set designed for high-strength bolted connections in industrial, mechanical, and structural applications. Each stud is manufactured from Grade B7 alloy steel to ASTM A193 standards, providing excellent tensile strength and resistance to elevated temperatures. The 7/8-9 thread size follows Unified National Coarse (UNC) specifications with a 7B class of fit, ensuring consistent thread engagement and reliable clamping force. The uncoated finish leaves the steel bare, suited for applications where coating compatibility or field treatment is required. Licensed tradespeople and industrial maintenance technicians typically source these studs for flange assemblies, pressure vessel work, and heavy mechanical connections.

This package includes four studs, each measuring 6.5 inches in length with a 7/8-9 thread, along with eight matching nuts. The fully threaded profile allows for flexible positioning along the full length of the stud, making these fasteners well suited for through-bolt configurations in pipe flange assemblies, equipment mounting, and structural mechanical joints. The Grade B7 material designation makes these appropriate for both ambient and elevated-temperature service environments commonly encountered in industrial maintenance and process piping work.

Key Features

• 7/8-9 UNC thread size with 7B class of fit for consistent, reliable thread engagement
• Fully threaded along the 6.5-inch length for maximum positioning flexibility
• Uncoated finish suitable for applications requiring field coating or bare-steel fitment
• Package includes four studs and eight nuts for immediate use

Compatibility

Designed as a standard 7/8-9 UNC fully threaded stud for use in industrial flange assemblies, pressure vessel connections, and structural mechanical joints requiring Grade B7 alloy steel fasteners.

Installation Notes

Installation is typically performed by licensed millwrights, pipefitters, or industrial maintenance technicians. Always de-energize, depressurize, and lock out the system before removing or installing fasteners on pressure-bearing assemblies. Use calibrated torque equipment and follow applicable ASME, ANSI, or plant-specific torque procedures for the flange class and gasket type. Inspect threads for damage before installation and apply appropriate thread lubricant or anti-seize compound as required by the service specification.
