Value Collection B7SN0880475CP Threaded Stud Nut 7/8-9 Steel

Product Description

The VALUE COLLECTION B7SN0880475CP is a fully threaded stud and nut assembly manufactured from Grade B7 alloy steel to ASTM A193 standards. Each stud measures 7/8-9 thread size and 4-3/4 inches in length with a 7B class of fit, delivering the dimensional consistency and tensile strength required for bolted flange connections, pressure vessels, and structural fastener applications. The uncoated finish is standard for high-temperature and high-pressure service environments where coatings could compromise seating or chemical compatibility. Each package includes 4 studs and 8 nuts, providing matched hardware for immediate installation.

This stud and nut set is suited for industrial and commercial applications including pipe flange assemblies, pressure vessel closures, pump and valve installations, and structural bolting in mechanical and process piping systems. ASTM A193 Grade B7 studs are a widely specified fastener in HVAC mechanical rooms, industrial piping, and heavy equipment maintenance. Licensed pipefitters, millwrights, and mechanical contractors typically install this hardware in code-governed bolted joint applications.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 specification for high-strength bolting
• 7/8-9 thread size with 7B class of fit for consistent engagement and reliable torque transfer
• 4-3/4 inch stud length suitable for standard flange bolt patterns in industrial piping
• Uncoated finish compatible with high-temperature and chemical service environments
• Package includes 4 studs and 8 nuts, providing matched sets for complete flange assemblies
• UNSPSC Code 31163300 for procurement and inventory classification

Compatibility

Designed as a standard ASTM A193 Grade B7 fully threaded stud for use in industrial bolted flange and pressure vessel applications requiring 7/8-9 threaded fasteners with 7B class of fit.

Installation Notes

Installation of high-pressure flange studs should be performed by a licensed pipefitter or qualified mechanical contractor in accordance with applicable ASME and ANSI piping codes. De-energize, depressurize, and isolate the system completely before removing or installing any bolted joint hardware. Apply lubrication to threads only if specified by the flange or equipment manufacturer, as dry torque values differ from lubricated values. Inspect stud threads and nut seating surfaces for damage before assembly.
