PURPOSE: A blind rivet is provided to simultaneously perform a drilling work and a riveting work through a driver. CONSTITUTION: A blind rivet fastens a first panel to a second panel. A left-screw nut passes through the center of a cylinder(10) and a flange(12) is formed on the upper end of the cylinder. A screw unit coupled to a nut unit is formed on the outer circumferential surface of the body. For a head, a driver fastening groove(24a) is formed on the upper part of the body. A rivet core(20) consists of a drill blade, which is formed on the lower part of the body to be able to rotate anticlockwise. A protrusion is formed on the lower surface of the flange in a wedge shape and prevents slipping anticlockwise if the lower surface of the flange makes contact with the upper surface of the first panel.
