The stud bolts are used to connect the stable connection of mechanical equipment. The stud bolts are threaded on both sides, and the extruder screw in the middle is thick or thin. It is called: metal rod/shrink rod, also called double-headed screw. It is generally used in mining equipment, road bridges, vehicles, motorcycles, heating furnace steel frame structures, hanging towers, long-span steel frame structures and large buildings, etc. Tips for bolt manufacturers: Bolts refer to screws with a relatively large diameter, and they can also have no heads, such as stud bolts. Generally, it is not called "stud bolt" but "double-ended stud". The most common form of double-ended studs is that there are threads on both sides and a main rod in the middle. More common uses: foot bolts. Or places near the foot bolts. Thick connections, which cannot be achieved with ordinary bolts. Stud bolts are also one of the commonly used bolts, which mainly have the functions of tightening and connecting in industrial equipment, electronic equipment, ships and vehicles, and water conservancy and hydropower projects. Can be a good fixed item. The so-called studs refer to the threaded screw heads on both sides, and the extruder screw in the middle, there are thick and thin. The main function and application of its related stud bolts are shown in the following three aspects. 1. It is used when the main body is a large-scale equipment, and accessories need to be installed, such as rearview mirror, mechanical seal seat, reducer frame, etc. At this time, stud bolts are used, one end is screwed into the main body, and the other end carries a nut after the accessories are installed. Because the accessories are often disassembled, the threads will be damaged or damaged, and it is very convenient to use stud bolts to replace. 2. When the thickness of the connecting body is very large and the length of the bolt is very long, stud bolts will be used. 3. It is used to connect thick steel plates and areas where it is not convenient to use hexagonal bolts, such as concrete steel roof trusses, flat roof beam suspensions, double-rail beam suspensions, etc.
