Of course, the lack of domestic high-end bolt manufacturing equipment still needs to be taken seriously. After all, China cannot stay in the low-end industry forever, and climbing to the high end of the value chain is an inevitable choice.
What is a single-sided bolt? Why develop single-sided bolts? What is the role of the unilateral bolt?
One-side bolts can be used for one-side installation and one-side tightening. Therefore, no additional machining holes are required, and bolting can be completed without damaging other parts of the steel pipe. The problem can reduce the welding amount as much as possible, thereby saving the construction amount and labor cost, and has the characteristics of simple and convenient on-site construction and extremely small welding amount. At the same time, under certain conditions, its mechanical properties can be compared with traditional high-strength bolts, which is very suitable for the connection of steel pipe structures. The existing single-sided bolts have a maximum size of M39, which is suitable for structural engineering and has great application prospects.
