A bolt is called "bolt" in English and is basically used in places with pre-formed threads. A nut is called "nut" and is used in conjunction with a bolt, and the tool for working with it is usually a wrench

Only in this way can we use the screw in the most appropriate place. Because there are many types of screws, and among these screws, the performance of each type of screw is different.
