steel studbolt grade B7 size inch 16 centimeters

The B7 grade steel stud bolt with a 1/2 inch diameter and 16 cm length weighs approximately 0.28 kg. Its material is alloy steel with quench and temper heat treatment, providing high mechanical strength. The external thread diameter is 12.7 mm and the effective thread length is 40 mm. Thread depth is approximately 1.15 mm with a pitch of 1.27 mm. The thread design complies with ANSI/ASME B1.1 standards, ensuring uniform stress distribution at the joint.

The Rockwell hardness of the B7 stud bolt ranges from 32 to 36 HRC, offering excellent wear and fatigue resistance. Its tensile strength is around 1200–1250 MPa, allowing it to withstand axial loads up to 50 kN. Heat treatment and alloy structure increase service life and maintain stable performance under demanding industrial conditions.

The alloy steel material provides high resistance against fatigue and corrosion. Proper lubrication during installation ensures uniform stress distribution and reduces stress concentration. Deep threads and effective thread length enable high static and dynamic load capacity, ensuring reliable performance in industrial connections.
