Abstract

A self-tapping screw comprises a screw head and a screw body which is extended from the screw head along an axial. The screw body includes a sharp portion which is far from the screw head and a self-tapping thread portion between the sharp portion and the screw head. By the above-mentioned structure, just let the sharp portion dig at least two workpieces first, and then rotate the screw head, then it is able to combine the workpieces by the effect of the self-tapping thread portion. The invention has a characteristic of increasing the working efficiency.
