Abstract
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.
