Abstract: A method for producing a screw foundation (1) for anchoring building parts or structures in the ground, comprising the following steps: providing a tubular starting material (10) with a required length, laying a free end (12) of the tubular starting material (10) between at least two shaped elements (20), securing the tubular starting material (10) in its longitudinal direction, compressing the free end (12) of the tubular starting material (10) by moving together the at least two shaped elements (20), with the result that an at least partially tapering region (14) is formed on the free end (12) of the tubular starting material (10), and forming a screw-like or helical thread (16) on the at least partially tapering region (14).
