Abstract: A method for producing a thread in a workpiece can include producing a preliminary thread by removing material from the workpiece (e.g., with a cutting action), which produces a preliminary thread profile having two preliminary thread flanks and a preliminary thread root connecting the two preliminary thread flanks. The method can also include producing, in at least one second working step, a final thread having a final thread profile, which has two final thread flanks and a final thread root connecting the two final thread flanks. The final thread can be produced by plastic pressing-in of the material of the workpiece at least in a section of the preliminary thread profile by a predetermined volume. In one implementation, at least one of the preliminary thread flanks and at least one of the of the thread-forming profile are include at different inclination angles from each other.
