Value Collection B7S100C700 Fully Threaded Stud 1-8 Thread

Product Description

The VALUE COLLECTION B7S100C700 is a fully threaded stud machined from Grade B7 alloy steel with a 1-8 UNC thread form and a 7-inch overall length. The uncoated finish leaves the steel bare, making it suitable for applications where a secondary coating or plating will be applied in the field. The thread is cut to Class 2A tolerance, the standard external-thread fit class for general industrial and structural fastener work. At 1.31 pounds, this is a heavy-duty stud intended for high-load bolted assemblies. Mechanical contractors, millwrights, pipefitters, and structural tradespeople are the typical end users for this fastener size and grade.

This stud is used in industrial piping flanges, structural steel connections, pressure vessel assemblies, and heavy mechanical equipment mounting applications. The Grade B7 alloy steel designation is common in ASME and ASTM high-temperature and high-pressure bolting applications, making it a frequent choice in refineries, power plants, and process piping installations where elevated-temperature service is a concern. The 1-8 thread size is a coarse-pitch UNC configuration, widely available in compatible hex nuts and flanged nuts.

Key Features

• Grade B7 alloy steel construction for high-strength, high-temperature service
• 1-8 UNC coarse thread, Class 2A tolerance for reliable fit with standard nuts
• 7-inch overall length with full threading across the entire shank
• Uncoated finish compatible with field-applied platings or coatings
• Heavy-duty 1.31-pound fastener suited for structural and pressure-rated assemblies

Compatibility

Designed as a standard Grade B7 fully threaded stud for use with 1-8 UNC compatible hex nuts, heavy hex nuts, and coupling nuts in industrial bolting applications. No specific equipment model compatibility is stated by the manufacturer.

Installation Notes

Installation should be performed by a qualified mechanical contractor or pipefitter familiar with ASME or ASTM bolting requirements applicable to the assembly. Always verify torque requirements against the applicable engineering specification or flange standard before tightening. Wear appropriate hand and eye protection when handling large-diameter threaded fasteners. Inspect threads for damage before installation and do not force engagement if resistance is felt.
