Value Collection B7SN0880600CP Threaded Stud Nut 7/8-9 6in Steel

Product Description

The VALUE COLLECTION B7SN0880600CP is a fully threaded stud and nut fastener assembly designed for high-strength bolting applications in industrial, mechanical, and structural installations. Manufactured from alloy steel to Grade B7 material specification, this stud meets ASTM A193 standards for high-temperature and high-pressure service. The stud measures 7/8-9 thread size with an overall length of 6 inches and is supplied uncoated. Each package contains 4 studs and 8 nuts. The 7B class of fit provides a standard allowance for external threads, making installation and assembly straightforward in field and shop environments. Licensed mechanics, pipefitters, and millwrights commonly install these fasteners in flanged pipe connections, pressure vessels, and equipment mounting.

This stud and nut set is suited for use in industrial piping systems, pressure vessel assemblies, heat exchangers, and structural bolting where ASTM A193 Grade B7 compliance is specified. The 7/8-9 thread size and 6-inch length are common in medium-to-large flange bolt patterns found in refineries, power plants, water treatment facilities, and commercial mechanical rooms. Installers working to ASME B16.5 or similar flange standards will find this stud dimensionally compatible with standard bolt-circle patterns at this thread diameter.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 for high-strength, high-temperature service
• 7/8-9 thread size with 6-inch overall length covers common medium flange bolt patterns
• 7B class of fit on external threads ensures consistent thread engagement and assembly tolerance
• Uncoated finish suitable for field application of anti-seize, thread sealant, or customer-specified coating
• Package includes 4 studs and 8 nuts, providing a complete fastener set per package
• ASTM A193 compliance documented for use in pressure-rated and code-inspected installations

Compatibility

Designed as a Grade B7 ASTM A193 fully threaded stud replacement for standard 7/8-9 flange and structural bolting applications requiring high-strength alloy steel fasteners.

Installation Notes

Installation should be performed by qualified pipefitters, millwrights, or mechanical technicians familiar with ASME and ASTM fastener standards. De-energize, depressurize, and lock out the system before removing or replacing studs in pressurized assemblies. Apply a suitable anti-seize compound or thread lubricant per the job specification before torquing; final torque values must be determined by the engineer of record or applicable code, not assumed from fastener grade alone. Inspect threads for damage before installation and do not use studs with crossed, stripped, or corroded threads.
