The B7 grade steel stud bolt, size 1/2 inch and length 11 cm, is manufactured from chromium-molybdenum alloy steel with heat treatment and complies with ASTM A193 standards. The total length of this component is 110 millimeters, with a nominal thread diameter of 12.7 millimeters. The threads are designed in UNC form with a standard pitch of 13 TPI, ensuring full compatibility with class 2H nuts. The ultimate tensile strength of this stud bolt is approximately 860 megapascals, while its yield strength is around 720 megapascals. These properties ensure stable performance under extreme temperature and high-pressure conditions.
The surface of the B7 steel stud bolt, size 1/2 inch and 11 cm length, is precisely hardened to achieve approximately 35 HRC hardness. Galvanized or phosphate coating enhances corrosion and oxidation resistance. This stud bolt is widely used in oil, gas, petrochemical, and power plant applications. It is fastened using class 2H hex nuts, with a standard tightening torque of about 80 newton-meters.
