How can the stainless steel plate lock the screws?
Meaning: the self tapping screw hole without tapping hole, the screw head is different and sharp, the pitch is relatively large, and no dust silk attack a bit like, without tapping directly into the rotation, and this method is usually used for metal plastic.
Self tapping screw is a kind of screw with drill bit. It is drilled, tapped, fixed and locked by special electric tools. Self tapping screw is mainly used for sheet metal parts is connected with the fixed connection, such as color steel plate and color steel plate, color steel plate and purlin, wall beam connection, its penetration ability is generally not more than 6mm, the maximum not more than 12mm. Self tapping screws are often exposed to the outside, and they have strong corrosion resistance. The rubber sealing ring ensures that the screw is impervious to water and has good corrosion resistance.
It can be consolidated on the material, depending on its own thread, the consolidated body "tapping, drilling, squeezing and pressing" out of the corresponding thread, so that they closely cooperate with each other.
