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： In a workpiece joining method using a joining jig, a distal end portion of a bolt shaft is inserted into each hole of at least one workpiece, and a sleeve is disposed onto a distal end portion of each bolt shaft. Then, an upper die of the joining jig is lowered toward the workpiece supported on a lower die so that while the workpiece is being pressed toward base end portions of the bolt shafts, a tightening portion of each nose provided on the upper die draws the outer wall of the corresponding sleeve, thus tightening the sleeves. As the tightening process progresses, the tightened portion of each sleeve progressively enters a relief portion formed immediately above the tightening portion. The thrust of the noses does not directly acts on the bolt shafts in the direction of their axes, so that the joining jig can apply a sufficient tightening force without being restricted by the strength of the bolt shafts.
