Value Collection B7SN0880625CP Threaded Stud Nut 7/8-9 B7

Product Description

The VALUE COLLECTION B7SN0880625CP is a fully threaded stud and nut assembly for heavy-duty fastening applications in mechanical, industrial, and trade installations. Each stud measures 7/8-9 thread size at 6.25 inches in length, manufactured from Grade B7 alloy steel with an uncoated finish. The 7B class of fit provides the standard allowance for external threads used in high-strength bolted connections. This package includes four studs and eight nuts, making it suitable for flange, equipment mounting, and structural fastening tasks performed by millwrights, pipefitters, and mechanical contractors.

These studs are used in applications requiring high-strength, fully threaded fasteners that conform to ASTM A193 specifications. Common install scenarios include pressure vessel flanges, pipe flanges, pump and valve mounting, and heavy mechanical equipment anchorage. The coarse 7/8-9 thread pitch and B7 alloy steel composition make this assembly well suited for high-temperature and high-pressure environments typical in industrial and commercial mechanical systems. Uncoated finish is standard for applications where galvanic compatibility or field coating is handled separately.

Key Features

• Grade B7 alloy steel meets ASTM A193 standard for high-strength fastener applications
• Fully threaded 7/8-9 coarse thread pattern along the full 6.25-inch length
• 7B class of fit provides standard external thread tolerance for reliable mating
• Uncoated finish compatible with field-applied coatings or bare installation
• Each package includes four studs and eight nuts for complete assembly

Compatibility

Designed as a standard ASTM A193 Grade B7 fully threaded stud assembly compatible with 7/8-9 coarse-thread nuts and flanged connections requiring high-strength fasteners in industrial and commercial mechanical installations.

Installation Notes

Installation is typically performed by licensed pipefitters, millwrights, or mechanical contractors. Depressurize and isolate any piping, vessel, or equipment before disassembling or replacing fasteners. Follow applicable torque specifications from the equipment manufacturer or relevant codes such as ASME PCC-1 for pressure boundary bolted connections. Inspect threads for damage before installation and ensure mating nut threads are compatible with the 7B class of fit.
