A method for manufacturing sectional screw blanks, in which a circular sector blank is produced that is deformed in a stamp between a die with a screw working surface and a cylindrical roller by their jointing along the thickness of blank followed by rolling by a cylindrical roller through the thickness of blank of screw working surface up to forming the sectional screw blank. Further during rolling process twisting of the cross section of part of circular sector blank adjacent to the area of deformation is made prior to its attachment to the cylindrical roller over the length of an arc, which is limited by a central angle.
