Abstract

An anti-theft fastening device includes a knob and a screw, which extending through a central hole of the knob. The screw body has a driving head, a fastening portion and a neck formed therebetween. The invention is characterized in that the knob further comprises an annular flange extending from a bottom portion of the knob toward an axis of the central hole. The flange defines a driving hole through which the fastening portion of the screw is inserted under a rotating state, with the driving head resisting against the flange. The flange further includes a contact surface formed from a wall of the knob, and a stopper formed on an inner wall of the flange, where the contact surface and the neck of the screw are located. The stopper defines a space which is adapted to prevent the screw being disengaged from the knob.
