Value Collection B7S087C550 Threaded Stud 7/8-9 5.5in B7

Product Description

The VALUE COLLECTION B7S087C550 is a fully threaded stud in 7/8-9 UNC thread form with a 5.5-inch overall length. Manufactured from Grade B7 alloy steel in an uncoated finish, this stud is built to handle high-strength fastening applications where consistent thread engagement across the full length is required. The Class 2A thread fit provides a standard external tolerance suitable for general industrial and structural assembly. At 0.79 pounds, the stud is sized for demanding bolt-up work in mechanical, piping flange, and structural connections. Installers in HVAC, plumbing, and industrial maintenance commonly use B7-grade studs where elevated tensile strength and reliable clamping loads are needed.

This fully threaded stud is suited for flange bolting, equipment mounting, and structural fastening tasks in commercial and industrial environments. The 7/8-9 thread size and 5.5-inch body length make it appropriate for medium-to-heavy-duty assemblies including pipe flanges, pressure vessel connections, and equipment base plates. The uncoated steel surface is compatible with standard hex nuts and is ready for use as delivered. Maintenance technicians, pipefitters, millwrights, and mechanical contractors will encounter this stud size in a range of industrial service applications.

Key Features

Compatibility

Designed as a general-purpose fully threaded stud for industrial and mechanical fastening applications requiring a 7/8-9 UNC thread and 5.5-inch overall length. Suitable for use with any standard 7/8-9 hex nut.

Installation Notes

Installation should be performed by qualified mechanical, piping, or maintenance trade professionals familiar with fastener torque requirements for the specific joint application. Always verify thread fit and material compatibility with mating components before assembly. Confirm the assembly is de-energized, depressurized, and properly supported before replacing or installing studs in live systems. Follow applicable industry standards such as ASME PCC-1 for pressure boundary bolted flange joint assembly.
