摘要： A stud which is automatically fed so as to welded stably and properly, has a large electric contact surface with the collet, facilitates clip attachment, and maintains the engagement firmly after the attachment of the clip. A stud 1 extends upwardly into a rod-like form which is threaded on its periphery, and includes a welding tip at the lower end thereof for welding to a base member such as a panel so as to be used in mounting a member to be attached on the base member. The stud 1 is formed to be short in overall length and its welding tip is formed as a flange 4 whose diameter is larger than that of the rod-like body. A crest 6 of the screw 3 is formed flat. An upper flank angle 8 of the screw is formed large while a lower flank angle 10 of it is formed small. An edge 12 of an upper end 11 of the stud is chamfered.

摘要翻译： 自动进给以稳定焊接的螺柱与夹头具有大的电接触表面，便于夹子附接，并且在夹子的附接之后牢固地保持接合。 螺柱1向上延伸成在其周边上螺纹的杆状形式，并且在其下端包括用于焊接到诸如面板的基座构件的焊接尖端，以便用于安装待附接的构件 在基座上。 螺柱1形成为总长度短，其焊头形成为直径大于杆状体的直径的凸缘4。 螺钉3的顶部6形成为平坦的。 螺杆的上侧面角8形成较大​​，同时其下侧翼角10形成得较小。 螺柱的上端11的边缘12被倒角。
