Nuts are parts that tightly connect mechanical equipment. They can be connected with bolts of the same specifications through the internal threads. For example, an M4-P0.7 nut can only connect with an M4-P0.7 series bolt (in the nut, M4 indicates that the inner diameter of the nut is approximately 4mm, and 0.7 indicates that the distance between the two threads is 0.7mm); the same applies to American products, for example, a 1/4-20 nut can only be paired with a 1/4-20 screw (1/4 indicates that the inner diameter of the nut is approximately 0.25 inches, and 20 indicates that there are 20 threads per inch).
