A screw joining apparatus is provided to reduce dispersion of joining force and increase joining force by reducing friction between a screw seating surface and a screw thread. A first object(1) and a second object(2) to be joined abut each other, and a screw part(4) having a screw head(3) or a screw nut is positioned such that the first object and the second object are screw-coupled with each other. A screw holder(9) is coupled to the screw head or the screw nut correspondingly. A vibrator(5) is arranged in contact with the screw holder such that the vibrator generates vibration to be supplied to the screw head or the screw nut. A screw joining unit(6) is coupled onto the screw holder so as to supply rotating force to the screw part. |
