The stud bolt is a kind of fixing piece commonly used in the connecting piece. Its advantages are mainly reflected in the following aspects: 1. Significant effect The stud bolt has good fixation and sealing, that is to say, it can play a good role in fixing and preventing the loosening of the connecting piece. This requires its reasonable design, advanced manufacturing technology, and selection of high-quality materials to ensure its firmness and durability. The application of stud bolts is particularly important in some occasions where the requirements for fixing the connectors are particularly high. For example, in the fields of aviation, automobiles, ships, machinery, etc., stud bolts are required for some key parts of the connectors. 2. It is economical. Due to the simple structure and convenient operation of the stud bolt itself, it can complete mass production and reduce the manufacturing cost. Moreover, maijin's stud bolts are also easy to disassemble and maintain, which can greatly reduce maintenance costs. Moreover, its long service life can not only reduce the number of replacements, but also effectively reduce the cost and time cost caused by replacement or damage. 3. High safety factor The stud bolt mainly guarantees the reliability of its connecting parts through the pre-tightening force, so its ability to withstand external forces is very strong, and the safety factor is also high. In some occasions where the strength of the connecting parts is required to be high, the use of stud bolts can effectively improve the safety of the connecting parts. 4. Easy to maintain The operation of stud bolts is relatively simple, no professional skills are required, only ordinary maintenance personnel can complete it. In addition, because the stud bolts are easy to disassemble, maintenance personnel can conveniently inspect and repair the connecting parts, and replenish the pre-tightening force in time, thereby increasing the service life of the connecting parts. In short, stud bolts show a series of advantages in the fixation of connectors. It can not only bring economic benefits, but also ensure the safety and reliability of the joints, increase the service life, save resources and maintenance time costs. At present, stud bolts have become one of the necessary and important components in the field of connectors, and their continuous and good development will promote the further development and upgrading of connectors and machinery manufacturing industries.
