USE OF
The main purpose of the machine screw is to fasten the object.
The machine screw is the fastening principle of the screw. Most of the fasteners used between the shaft and the sleeve prevent the shaft and the sleeve from changing position during the use.
It can be used to prevent the relative movement between the shaft and the sleeve. In some cases, the top wire is easy to disassemble. For example, the two parts are closely matched and can be separated by the top wire.
Commonly used in mining, metallurgy, textile, conveying machinery, etc. It is suitable for occasions where the required equipment and components are simple, with a certain degree of self-aligning, easy to install, and a double-structured sealing device that can work in harsh environments. The structure is diverse, versatile and interchangeable.
