Stud fasteners have threads at both ends, and a light screw in the middle, without a head, and are also called studs. The production materials are mostly Q235 steel, 35Cr, 45Cr, 35CrMoA, etc. Different wires determine the strength grade of the stud bolts. The strength grade of the stud bolts made of Q235 steel is 4.8, the 35Cr stud is 8.8, and the 45Cr is double The head bolt is class 10.9, and the strength of the stud bolt produced using 35CrMoA is class 12.9.

Application range of stud bolts:

Stud bolts can be used in fields such as automobiles, motorcycles, mining machinery, boiler steel structures, bridges, suspension towers, large-span steel structures and large buildings.

Surface treatment of stud bolts:

In order to prevent the bolts from rusting and prolong their service life, the bolts are generally surface treated. The stud bolts are mostly blackened, and some of them are galvanized.
