摘要：
A screw has a thread (3), whose front and rear flanks have a different angle with respect to the screw longitudinal axis. The screw tip (2) can contain a scraping groove (6), which extends as a notch in the screw longitudinal direction. In the front, conically tapering area of the screw the thread course is constructed symmetrically and extends up to the tip.
