Product Description

  Self-tapping screw is a kind of screw with a drill bit, through the construction of special electric tools, drilling, tapping, fixing and locking are completed at one time. Self-tapping screws are mainly used for the connection and fixation of some thin plates, such as the connection of color steel plate and color steel plate, the connection of color steel plate and purlin, wall beam, etc., the penetration capacity is generally not more than 6mm, the maximum is not more than 12mm. Self-tapping screws are often exposed outdoors and have strong corrosion resistance; The rubber sealing ring can ensure that the screw is not seepage and has good corrosion resistance. Self-tapping screws are usually described by three parameters: screw diameter series, number of threads per inch length, and screw length. There are two screw diameter grades: 10 and 12, and the corresponding screw diameters are 4.87mm and 5.43mm, respectively. The number of threads per inch length has 14, 16, 24 three levels, the more threads per inch length, the stronger its self-drilling ability
