A continuous screw tightening machine which is capable of precisely feeding single-part screws without the need for using a conventional screw gang element containing a number of screws arranged at prescribed intervals in a row by means of a belt-like member, and is capable of continuously and efficiently screwing-in screws into a plate material or other object. It is a continuous screw tightening machine with which a driving machine 4 equipped with a grip handle 2 is mounted, and which comprises a tightening machine main body 3 with which a bit 7 for screw tightening is removably connected to the driving machine 4 through a reduction gear and a clutch; and a screw feed mechanism through which the bit 7 is rotatably inserted and which sequentially feeds a screw to the position where tightening operation is carried out by the bit 7, in synchronism with the sliding in the longitudinal direction of the tightening machine main body 3 involved in the screw tightening operation by the bit 7, and comprises a screw feed mechanism main body 6 which is connected to the front of the tightening machine main body 3 so as to be slidable in the longitudinal direction, a screw supply mechanism 110 which continuously supplies a number of single-part screws in sequence to the screw feed mechanism under the force of gravity, and a tip block 12 which is connected to said screw feed mechanism main body, providing a surface to be contacted with an object.
