The wood or plastic screw (10) comprises a head (12), a tip (26), a cylindrical shaft (14) with a thread and a conical tip section (24), which form the transition of the shaft to the tip. The screw has two threads (20,22), from which the former thread extends itself up to the tip, and the latter thread ends before the tip. The latter thread in the tip section has an angled end section (30). The latter thread is formed in the area of the shaft. |
