Value Collection B7S087C800 Threaded Stud 7/8-9 8 in Grade B7

Product Description

The VALUE COLLECTION B7S087C800 is a fully threaded stud designed for heavy-duty fastening applications where continuous thread engagement along the entire shank length is required. Manufactured from Grade B7 alloy steel in an uncoated finish, this stud measures 8 inches in overall length with a 7/8-9 UNC thread form and carries a Class 2A thread fit tolerance, indicating a standard external thread allowance suited for general industrial and structural fastening. At 1.14 pounds, it provides substantial material cross-section for load-bearing installations. Machinists, pipefitters, millwrights, and maintenance technicians commonly install this type of fastener in flange assemblies, machinery mounts, and structural connections.

This fully threaded stud is suited for use in industrial, mechanical, and structural applications where a through-bolt or double-nut configuration is needed. Grade B7 alloy steel is a common material specification in ASME and ASTM fastener standards, making this stud appropriate for pressure flange assemblies, pipe flanges, pump housings, and general equipment mounting where controlled preload and high tensile strength are priorities. The uncoated surface is compatible with standard plated nuts and washers.

Key Features

• 7/8-9 UNC thread size provides coarse-thread engagement suitable for structural and industrial loads
• 8 inches overall length with full thread coverage along the entire shank
• Grade B7 alloy steel construction offers high tensile and yield strength
• Class 2A thread fit ensures standard tolerance for use with Class 2B nuts
• Uncoated finish maintains dimensional accuracy without plating buildup

Compatibility

Designed for use with standard 7/8-9 UNC Class 2B hex nuts and washers in general industrial, structural, and mechanical fastening applications.

Installation Notes

Installation of fully threaded studs typically requires a double-nut or stud-driving method to thread the fastener into tapped holes or through-holes without damaging the thread form. Always confirm the mating thread class and material compatibility before installation. Apply appropriate torque using calibrated tooling and follow relevant ASME, ASTM, or facility-specific fastener installation procedures. De-energize and de-pressurize any system before replacing load-bearing fasteners in live assemblies.
