PROBLEM TO BE SOLVED: To perform a machine screw fastening work only by one hand by using air for a machine screw mounting unit to be mounted to a bit, and mounting a machine screw suction unit to the bit itself. SOLUTION: A device for sucking a machine screw 13 with vacuum pressure of air and for mounting the machine screw 13 to the tip of a bit 4 is mounted to the bit 4 itself. Otherwise, a device that grabs the machine screw 13 with spring pressure or rubber pressure and mounts the machine screw 13 to the tip of the bit 4 is mouthed to the bit 4 itself. Thus, because a manner is taken that the head of the machine screw 13 floats up over a machine screw plate, the machine screw 13 can be certainly caught. Therefore, this device can mounted to any screwdriver with a single operation, fastening work of the machine screw 13 can be performed only by one hand, and this device can be used for any assembling work.
