Self-drilling tapping screw (self-drilling screw)
People have made statistics: among the ten expenses which constitute the total assembly cost, the highest one includes the machining of holes. In practical application, self tapping screws need to process prefabricated holes. And in order to make the prefabricated holes play a good effect in practical application, it is necessary to control the size of these holes in a very strict range. In the early 1960s, self-drilling and tapping screws appeared. As there is no need to process prefabricated holes, it is a big step forward in reducing assembly costs. Generally speaking, the self-drilling and tapping screws achieve drilling, tapping and fastening in one operation.
