Construction operation technology Nuts are parts that closely connect mechanical equipment. Nuts and screws of the same specification can only be connected together through the inner thread. For example, M4-0.7 nuts can only be matched with M4-0.7 screws (in the nut, the inner diameter of M4 finger nut is about 4mm, and the distance between the two thread teeth of 0.7 finger is 0.7mm). The same is true for American products. For example, 1/4-20 nuts can only be matched with 1/4-20 screws (1/4 finger nuts have an inner diameter of about 0.25 inch and 20 teeth per inch). Scope of application Hexagon nuts and screws, bolts, screws with the use of each other, play the role of connecting fastening parts. Keywords: Hex nuts
