The invention relates to the technical field of thread forming devices, and provides a screw and bolt thread forming device and method. The multiple first thread rolling parts are arranged, and the multiple first thread rolling parts are annularly arranged on the rack; the second thread rolling parts are arranged on the rack in a sliding mode and located on the inner sides of the first thread rolling parts, and the second thread rolling parts make sliding contact with the first thread rolling parts; and the driving mechanism is arranged on the rack and used for driving the second thread rolling part to move along an annular path. By means of the technical scheme, the problems that in the prior art, most of existing screws and bolts are subjected to thread forming through thread rolling plates, but thread rolling work cannot be carried out when a movable thread rolling plate returns after thread rolling is completed through the existing thread rolling plates, and thread rolling cannot be carried out on differe
