摘要： A tapping screw fastened to a subject member in which a thread portion formed in a shaft portion of the tapping screw is used to form a female screw thread in a prepared hole of the subject member. An angle of a thread ridge is approximately 30 degrees, a plurality of notches are formed in a top portion of the thread portion over a predetermined range of an entire length of the shaft portion, and a joint portion for connecting the top portion and a bottom portion of the thread portion is formed to have a circular arc shape in an area having a smaller diameter than a diameter of the prepared hole of the subject matter, as viewed in a cross section including a shaft center of the tapping screw.

摘要： 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.
摘要翻译：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。

摘要： A bolt is provided with a head part and a shank part. The shank part includes a first constant diameter cylindrical part, a transition part, a cylindrical connection part, and a second constant diameter cylindrical part concentrically extending from the first constant diameter cylindrical part to the second constant diameter cylindrical part. The first constant diameter cylindrical part has a screw thread with a predetermined pitch formed on the side surface thereof. The transition part has a tapered shape and has a screw thread with a predetermined pitch formed on the side surface thereof. The cylindrical connection part has a diameter smaller than that of the first constant diameter part. The second constant diameter cylindrical part has a diameter smaller than the first constant diameter part, and has a screw thread with a predetermined pitch formed on the side surface thereof. The crest part of the screw thread formed on the side surface of the transition part is truncated.

摘要： In a bolt of the present invention, a guide portion having a small diameter is formed at the distal end of a shaft portion and ridge having an inverted direction screw configuration relative to the ridge formed on a constant diameter portion is formed. When the bolt is inserted obliquely into a nut and the ridge gets into engagement with a female screw portion of the nut, an effect of floating the bolt is generated, and the bolt cannot be driven into the nut unless it is set in an appropriate tightening posture. Consequently, biting and seizing of the bolt to the nut can be prevented securely. If the ridge is formed into a double threaded screw having an inverted direction screw configuration, the effect can be further intensified.
摘要翻译：在本发明的螺栓中，形成具有小直径的引导部分，在轴部的远端形成有相对于形成在恒定直径部分上的脊的反向螺杆构造的脊。当螺栓倾斜插入螺母并且脊与螺母的内螺纹部分接合时，产生浮动螺栓的效果，并且螺栓不能被驱动到螺母中，除非其被设定在适当的紧固姿势。因此，可以可靠地防止螺栓咬合到螺母上。如果脊形成为具有反向螺杆构造的双螺纹螺钉，则可以进一步增强其效果。

摘要： In a bolt of the present invention, a guide portion (116) having a small diameter is formed at the distal end of a shaft portion (15) and ridge (31) having an inverted direction screw configuration relative to the ridge (30) formed on a constant diameter portion (115) is formed. When the bolt (1) is inserted obliquely into a nut (100) and the ridge (31) gets into engagement with a female screw portion (105) of the nut (100), an effect of floating the bolt (1) is generated, and the bolt 1 cannot be driven into the nut 100 unless it is set in an appropriate tightening posture. Consequently, biting and seizing of the bolt 1 to the nut can be prevented securely. If the ridge (31) is formed into a double threaded screw having an inverted direction screw configuration, the effect can be further intensified.
