Finally, I came back to the question, why are high-end bolts imported in large quantities?

In fact, although many domestically produced equipment cannot meet the manufacturing requirements of high-end bolts, these manufacturing equipments can be imported. Many domestic manufacturers use imported equipment in large quantities, the equipment is not bad, and the process is also very stable, and it is fully capable of manufacturing high-end bolts. Moreover, there are many foreign high-end bolt companies that have set up factories in China. Their equipment and craftsmanship are the same as those in foreign countries. So why do many applications prefer to import rather than use domestic bolts? Take the automobile industry as an example. The automobile industry is one of the industries with the highest number of high-end standard parts imported from China.
