B7 Black Oxide Stud Bolt with 2H Nuts is a heavy-duty industrial bolting set designed for flange connections, piping systems, valves, pressure vessels, heat exchangers, pumps, petrochemical plants, refineries, oil & gas facilities, power plants, marine applications, chemical processing plants, and general high-strength fastening requirements.

This fastening set normally consists of ASTM A193 Grade B7 stud bolts supplied together with ASTM A194 Grade 2H heavy hex nuts. B7 stud bolts are commonly selected for demanding industrial service where strength, correct specification, reliable thread engagement, and long-term bolting performance are important. 2H nuts are commonly paired with B7 studs for flange, pressure equipment, and plant maintenance applications.

The black oxide finish provides a clean black appearance and helps reduce light surface oxidation in selected environments when properly maintained or protected. It is often selected for industrial identification, cleaner appearance, and applications where a dark finish is preferred. For outdoor, chemical, marine, or highly corrosive environments, final coating selection should be checked according to project specification.
