Main applications of stud:
1. When the main body is large-scale equipment, it is necessary to install accessories, such as sight glasses, mechanical seal seat, reducer frame, etc. At this time, one end of the stud bolt is screwed into the main body, and the other end is provided with a nut after installing the accessory. Since the accessory is often disassembled, when the main body and the accessory are directly connected by bolts, the main body thread will wear or be damaged over time, and it is very convenient to use the stud bolt for replacement.
2. When the connecting body is thick and the bolt length is very long, the stud bolt will be used. In practical work, external loads such as vibration and change, high temperature creep of materials and so on will reduce friction force, and the positive pressure in the thread pair will disappear at a certain moment, and the friction force will be zero, thus making the thread connection loose. If it is repeatedly acted, the thread connection will relax and fail. Therefore, it is necessary to prevent loosening, otherwise it will affect normal work and cause accidents.
