Nuts are parts that are tightly connected with mechanical equipment. Only through internal threads can nuts and bolts of the same specifications be connected together. For example, M4-P.7 nuts can only be connected with M4-P.7 series bolts (in nuts, the inner diameter of M4 nuts is about 4mm, and the distance between 0.7 fingers and two threaded teeth is 0.7mm). Similarly, for example, 1/4-20 nuts can only be matched with 1/4-20 nuts (1/4 finger nuts have an inner diameter of about 0.25 inches, 20 fingers have 20 teeth per inch).
There are many kinds of nuts, but also nuts of different materials. Each type of nut has different specifications, and each type of screw has its mechanical properties and functions.
