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).
