摘要： A screw has a shaft section which extends axially, a screw thread at the shaft section, which screw thread has thread turns that extend radially starting from the shaft section, a screw tip section which connects to the shaft section, at least one first scraping edge at the screw tip section, and at least one second scraping edge in a region of the shaft section adjacent to the screw tip section. The at least one first scraping edge and the at least one second scraping edge are spaced at a distance from each other and extend in an axial direction over different areas of the screw.
