The thread rolling machine has rolling jaws (1,2). They have opposing surfaces provided with inclined ridges (4) representing the rectified threads extending about half of the jaw height. The rest of the jaw height has set back surfaces with ramp-like ridges (5a,5b) with suitable profiles to give the tip (10) of the screw (11) the required shape while cutting off any surplus material (13) from the tip of the screw blank. This is achieved while the two jaws (1,2) are moved in opposite directions with the screw (11) placed between the two ridged faces (4).
