Abstract

The application provides a screw threaded fastening component, which comprises a stud bolt having an external thread, a first connecting part into which a first screw threaded hole adaptive to the stud bolt is formed, and a second connecting part into which a second screw threaded hole adaptive to the stud bolt is formed, and a threaded direction of the second screw threaded hole is against the threaded direction of the first screw threaded hole. The first connecting part and the second connecting part are assembled on two ends of the stud bolt through the first screw threaded hole and the second screw threaded hole, respectively, and the first connecting part is engaged against the second connecting part when the stud bolt is rotated in a direction. The stud bolt is contained in the first screw threaded hole and the second screw threaded hole when the first connecting part and the second connecting part are engaged completely. The application omits the screw head ordinarily designed in screw threaded connection such that the space is saved and the affection on the appearance of the product caused by the exposed screw head can be prevented.
