摘要： A high-speed forming tap (1) for cutting and forming a female screw by cutting edges (E) of a screw portion (2) fed in synchronous with the rotation of a machine tool. The high-speed forming tap is characterized in that chamfers (CF) are provided at a bevel lead (2a) of the screw part (2). The chamfers (CF) start from the cutting edge (E) and are provided along ridgelines (R) between a crest face (2e) and flanks, or a following flank (2c) and a leading flank (2d). This structure enables the shape of the edges of the tap leading portion to be stably maintained and high-speed, smooth female screw cutting with high accuracy, and provides a tap with long life.

摘要： A shape of a screw for fastening thin-sheets or thin-walled parts is characterized in that a value of ratio (P/D) of a pitch (P) to each of nominal diameters (D) of coarse thread in the shape of screw thread is reduced as compared to values of ratio of pitches to a corresponding nominal diameter of coarse thread in known kinds of screw thread standard, and the multiple number of thread start is set to 2 or more. Thus, for the thin-sheets and thin-walled parts in which three engaging ridges of screw threads cannot be secured when current metric coarse thread screw is used, the shape of the screw thread advantageous in strength and excellent in loose torque after vibration can be provided, since screw fastening is stabilized more than a case in which the metric coarse thread screws are used.
摘要翻译：用于紧固薄板或薄壁部件的螺钉的形状的特征在于，螺距形式的粗螺纹的螺距（P）与公称直径（D）之间的距离（P）的比值（P / D）与已知种类的螺纹标准中的螺距比与粗螺纹的相应公称直径的值相比，螺纹减少，多次螺纹起始设定为2以上。因此，对于使用当前的公制粗螺纹螺钉时，不能确保螺纹的三个接合脊的薄板和薄壁部件，具有强度和振动后的松散扭矩优异的螺纹形状可以是因为螺钉紧固比使用公制粗螺纹螺钉的情况更稳定。
