SA193-B7 Heavy Double End Stud

Double End Stud (English name: double end Stud) refers to a cylindrical fastener with threads at both ends. Widely used in power, chemical, oil refining, valves, railways, bridges, steel structures, automotive parts, machinery, boiler steel structures, suspension towers, large-span steel structures, and large buildings. The diameter, length, and quantity of the double head bolts should meet the requirements, and the type and material of the double head bolts are determined by the grade. There are two types of commonly used double head bolts (also known as full thread studs), which are divided into coarse and fine teeth. Coarse regular threads are represented by M and nominal diameter, while fine regular threads are represented by M and nominal diameter × Pitch representation. According to the fastener standard, M36 bolts can use coarse thread, and M36 and above diameters can use fine thread, with a pitch of 3. Bm=1d double head studs are generally used for the connection between two steel connectors; Double headed studs with bm=1.25d and bm=1.5d are generally used for the connection between cast iron and steel connectors; Bm=2d double head studs are generally used for the connection between aluminum alloy connectors and steel connectors. The former type of connector mentioned above has internal threaded holes, while the latter type of connector has through holes. The threads at both ends of equal length double head studs should be matched with nuts and washers for two connectors with through holes. One end of the welding stud is welded to the surface of the connector, and the other end (threaded end) passes through the connector with a through hole. Then, cover the washer and Screw on the nut to connect the two connectors as a whole,Heavy Double End Stud,B7 Heavy Double End Stud,ASTM Heavy Duty Double End Studs,SA193-B7 Heavy Double End Stud
