Disclosed is a method for manufacturing wide-strip screw blanks, in which a toothed blank is cut consisting of grooves and teeth plates connected by grooved cross-pieces, and then the grooved cross-pieces are asymmetrically reduced by their width with rollers, which form a gap between them to form a helix spiral followed by its calibration for a pitch. During asymmetric reduction of the grooved cross-pieces the electrical current is simultaneously supplied to the deformation zone transversely to the rolled grooved cross-piece, wherein the current density is determined by the formula.
