New description: [New technical field] The creation of this case is a drill tail design with two static points at the front end of the drill tail screw. [Prior Art] The structure of the self-drilling screw differs depending on the material of the locking object, but the purpose of the drilling is to be quick and labor-saving when screwing in and the firming effect after screwing; The positioning stability of the drilling point and the smoothness of the drilling directly affect the speed of the screw screwing and the amount of torque to be applied. If the screw itself is drilled, the β can be used to produce excellent drilling point positioning. Sex and the rapid cutting effect of the drilling, the drilling speed of the screwing is inevitably light and rapid, and the required torque is also small.
