Double End Threaded Stud Screw Bolt

Double End Threaded Stud Screw Bolt DIN 835, also referred to as stud screws or studs, possess threads on both ends. The middle Screw portion can be either thick or thin. The key characteristic of this type of bolt is that the length (bm) of its threaded end is equivalent to twice its diameter (d), namely, bm = 2d. Double End Threaded Stud Screw Bolts DIN 835 are extensively utilized in diverse machinery and equipment that demand fixed connections, such as mining machinery, bridges, automobiles, motorcycles, boiler steel structures, hanging towers, long-span steel structures, and large buildings. They are particularly suitable for locations where the thickness of the connecting body is substantial, the bolt length is long, thick plate connections are required, and where the use of hexagonal bolt connections is inconvenient.
