Abstract

The screw has a head (1) with a tool insertion area (2) on top, a short plane cylindrical segment (3) adjacent to the head (1) and a threaded main shaft (4). The short tip (5, 6) is pointed and also threaded. The outer diameter of the plane area (Da2) is slightly smaller than the outer diameter (Da1) determined by measuring the threaded segment (4). The core diameter (DK) is kept of the same dimension along the shaft facilitating the production of the screw by applying the same pressure level on the full length.
