摘要 |
The screw has a shank (1) that is formed with a conical screw spike (2) at one end and with a screw head (3) at the other end. The shank is formed over a part of its length with a screw thread, where threads (4a) of the screw thread are formed as triangular form approximate to the cross section. A part of the threads is formed in a direction of rotation of the screw with constant cross section with a wave-like process. The threads are formed at outer edges with notches. A shank part (1a) is closed at the head of the screw without the thread. |
