Stud bolt is also called double head screw or stud. It is used to connect the fixed link function of machinery. Both ends of the stud bolt are threaded, and the middle screw is thick and thin. Generally used in mining machinery, bridges, automobiles, motorcycles, boilers, steel structures, hanging towers, large span steel structures and large buildings.
There are many kinds of surface treatment of bolts, such as electroplating, blackening, oxidation, phosphating, non electrolytic zinc coating, etc. However, electroplating fasteners occupy a large proportion in the actual use of fasteners. Especially in the automobile, tractor, household appliances, instrumentation, aerospace, communications and other industries and fields are more widely used. However, for threaded fasteners, it also needs to meet the interchangeability of threads, which can also be called screwing in here.
