More Information
Summary:A method for producing a screw foundation for securing elements in the ground, provides a cylindrical tube as an initial form and a conical front portion tapering to an insertion tip is then molded on to the cylindrical tube using a non-cutting process, the front portion being provided at least in some regions with a thread-like contour for screwing into the ground. An inner contour for a screwing tool is formed integrally in a rear end of the tube by flow forming, and the front portion and the thread-like contour are formed exclusively by flow forming.
