The B7 steel stud bolt, size 1/2 inch 9 cm, is manufactured from chromium-molybdenum alloy steel and produced according to ASTM A193 standards. The total length of this component is 90 millimeters, with a nominal thread diameter of 12.7 millimeters. The threads are designed in UNC profile with a standard pitch of 13 TPI, ensuring full compatibility with class 2H hex nuts. The ultimate tensile strength of this stud bolt is approximately 860 megapascals, while its yield strength is around 720 megapascals. These specifications ensure high performance under extreme temperature and high-pressure conditions.

The surface of the B7 stud bolt, size 1/2 inch 9 cm, is precisely heat-treated, achieving a hardness of approximately 35 HRC. Galvanized or phosphate coating on the surface enhances corrosion and oxidation resistance. This stud bolt is widely used in oil, gas, petrochemical, power plant, and high-pressure structural applications. It is fastened using class 2H hex nuts, with a standard tightening torque of about 78 newton-meters.
