Value Collection B7S087C400-D Threaded Stud 7/8-9 4in Steel

Product Description

The VALUE COLLECTION B7S087C400-D is a fully threaded stud designed for high-strength fastening applications where a continuous thread profile is required along the entire length of the fastener. Manufactured from Grade B7 alloy steel with an uncoated finish, this stud measures 4 inches in overall length with a 7/8-9 thread size and a Class 2A thread fit. The Class 2A designation indicates a standard external thread tolerance suitable for general industrial and structural assembly. At 0.57 pounds, it is a solid, single-piece fastener suited for use by millwrights, pipefitters, maintenance technicians, and structural fabricators.

This fully threaded stud is well suited for industrial, mechanical, and structural applications where double-nut or flange-style assembly is required. The 7/8-9 UNC thread pattern is a common coarse-thread configuration found in heavy equipment, pressure vessel assembly, pump mounting, and general structural steel work. Grade B7 material meets the elevated strength requirements typical of high-load bolted connections. It is sold and packaged as a single unit, making it practical for maintenance replacement or low-volume fabrication work.

Key Features

• Fully threaded 4-inch length allows maximum engagement at both ends without a plain shank
• 7/8-9 UNC coarse thread is a widely used industrial fastener standard
• Grade B7 alloy steel construction provides high tensile strength for demanding load applications
• Class 2A thread fit ensures standard external thread tolerance for reliable mating with Class 2B nuts
• Uncoated finish suitable for use as-is or for field application of coatings or lubricants

Compatibility

Designed as an OEM-style or aftermarket replacement fully threaded stud for industrial and structural bolted assemblies requiring a 7/8-9 UNC thread pattern and 4-inch overall length.

Installation Notes

Installation is typically performed by millwrights, pipefitters, or maintenance technicians using standard hex nuts, washers, and torque wrenches. Always de-energize, depressurize, or isolate the assembly before removing or replacing fasteners in active systems. Follow applicable ASME, AISC, or equipment manufacturer torque guidelines for the specific joint application. Inspect mating nut threads and seating surfaces before installation to ensure proper thread engagement and load distribution.
