For the 1-1/8" x 200mm cadmium plated stud bolt and nut, the standard configuration typically involves an ASTM A193 Grade B7 alloy steel stud paired with two ASTM A194 Grade 2H heavy hex nuts. Cadmium plating is specifically chosen for its exceptional corrosion resistance in marine and offshore environments, as well as its low friction coefficient, which ensures predictable torque during installation.
