Stud is used to connect the fixed link function of the machine, both ends have threads, the middle is a screw, there are thick and thin. The thick one is called the thick rod or type A, and the thin one is called the thin rod or type B. Mainly used for connecting parts too thick do not use bolts or due to frequent disassembly should not use screw connection occasions, the stud is usually one end screwed into the screw hole, one end is connected with a nut. Each end of an equal length stud is configured with nuts. Generally used in mining machinery, bridge construction, automobiles, motorcycles, boiler steel structure, hanging tower, long-span steel structure and large buildings, flange connectors, machinery and equipment, pipelines, pump plants, motor plants, construction projects, sewage pipes, machine tools, engines and so on.

1. Transmission function: The rack can convert rotational motion into linear motion. This conversion is crucial in many mechanical devices, such as machine tools, automotive steering systems, etc. 2. Positioning function: In some special machinery and equipment, it is necessary to move objects up and down along a straight line, and the rack can play a positioning role. The vertical teeth on the rack can keep the machine stable during movement and ensure that it can move up or down in a straight line 3. Support and reinforcement function: Tooth strips play a role in supporting weight and strengthening the firmness at the intersection of the upright and horizontal beams of furniture. It is similar to wooden components in architecture, which can enhance the overall stability of furniture In summary, dental strips have different roles in different fields. In the field of machinery, it is mainly responsible for transmission, positioning, and control; In the field of furniture, it plays multiple roles of support, reinforcement, and decoration.

1. A threaded rod is defined as a machined part with external threads on the rod body. It is usually used to join two or more parts together and provide some tensile strength. In general, threaded rods are usually galvanized to improve their corrosion resistance. 2. The DIN975 standard specifies the requirements for the size, material and physical properties of the threaded rod to ensure its quality and interchangeability. This standard has a wide range of applications in construction, machinery, automotive, aerospace and electronics

1. A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod.They are designed to be used in tension. 2. First, threaded rods can be used as transmission elements in mechanical devices. Second, threaded rods can also be used to fasten structures. In addition, threaded rods can also be used in adjustment devices. In addition, threaded rods also play an important role in the field of scientific experiments and measurements. 3. Wide application: Threaded rods are usually used in conjunction with nuts. By rotating the threaded rods, the purpose of clamping, fixing or adjusting objects can be achieved.It is widely used in engineering, construction and scientific experiments. Its main function is to support or connect mechanical components. Through threaded rods, mechanical components can be stably supported, reliably connected, powered, and precisely adjusted.
