    • The tapping screw has a screw thread having a non-circular shape. Accordingly, when the tapping screw is screwed into the prepared hole formed in the attached member such as a steel plate, etc., the contact area of the screw thread and the circumferential face of the prepared hole of the attached member can be reduced in comparison with the screw thread having a circular outer shape. Accordingly, the screwing torque can be reduced. Further, since the top portion of the screw thread of the square outer shape has a rising shape without being broken, the biting property of the screw thread with respect to the prepared hole formed in the attached member is improved so that a female screw can be precisely threaded on the inner circumferential face of the prepared hole by the screw thread.
    • 自攻螺钉具有非圆形的螺纹。 因此,当自攻螺钉旋入到诸如钢板等的安装构件中形成的预制孔中时,可以减少螺纹与安装构件的预制孔的圆周面的接触面积 螺纹具有圆形外形。 因此,可以减小旋拧扭矩。 此外,由于方形外形的螺纹的顶部具有上升的形状而不会断裂,所以提高了螺纹相对于安装部件中形成的预备孔的咬合性能,使得内螺纹可以 通过螺纹精确地拧入预制孔的内周面上。
