Value Collection B7SN0881125CP Threaded Stud Nut 7/8-9

Product Description

The VALUE COLLECTION B7SN0881125CP is a fully threaded stud with nuts, manufactured from Grade B7 alloy steel in an uncoated finish. Each stud measures 7/8-9 thread size and 11.25 inches in length, conforming to a 7B class of fit for reliable thread engagement in high-load fastening applications. This stud and nut assembly is used wherever threaded rod anchoring, flange bolting, or structural clamping is required. Installation is typically performed by millwrights, pipefitters, or general mechanical contractors working on industrial or commercial equipment.

This package contains 4 studs and 8 nuts, making it suitable for multi-point bolting jobs such as pipe flange connections, pressure vessel assemblies, pump mounting, and heavy equipment maintenance. The 7/8-9 coarse thread profile provides strong engagement in steel and cast iron applications. The uncoated finish is standard for environments where galvanic considerations or applied coatings will be handled on-site after installation.

Key Features

• Grade B7 alloy steel construction for high-strength, high-temperature fastening service
• 7/8-9 coarse thread with 7B class of fit for consistent thread tolerance and reliable engagement
• 11.25-inch length accommodates thick flange or sandwich-stack bolting configurations
• Uncoated finish — field coating or plating can be applied as required by the application
• Package includes 4 studs and 8 nuts — no separate hardware required for typical two-nut installations

Compatibility

Designed as an OEM-style replacement or general-service fastener for industrial and mechanical assemblies requiring 7/8-9 fully threaded studs with Grade B7 material specification.

Installation Notes

Installation should be performed by a qualified millwright, pipefitter, or mechanical technician. Depressurize and de-energize all systems before removing or installing studs in flange or pressure vessel applications. Follow applicable ASME, ANSI, or plant-specific torque procedures for stud tensioning — do not estimate or improvise torque values for pressure-bearing joints. Inspect threads for damage before installation and ensure mating nuts run freely by hand before applying final torque.
