Abstract
- 18 - 5 \"Screw element\" Abstract The present invention relates to a screw element (1), 10 comprising a threaded shank (2) and a screw tip (4), which is configured on one shank end, and a screw head (5), which is configured on the opposite shank end and has a force-application means (7), and having a screw thread (12) which runs on the threaded shank (2) and 15 the screw tip (4). The screw tip (4), when viewed in the screw-in direction (Z), has a front first tip portion (4a), which tapers off towards the end of the screw element, and a second tip portion (4b), which is adjacent to said first tip portion (4a), having, when 20 viewed in the cross section, a polygonal cross section, the enveloping circle diameter (dh) of which is larger than a core diameter (d ) k of the first tip portion (4a). The first tip portion (4a) has a circular cross section. On the transition between the first tip 25 portion (4a) and the second tip portion (4b), at least one end edge face (9) which, in relation to a screw centre axis (X-X), is radially oriented in the sense of a diameter enlargement and which terminates in a vertex (15) of the polygonal cross section, which lies on the 30 enveloping circle of the second tip portion (4b) is configured. The screw thread is configured without interruption over the first and second tip portions (4a, 4b) of the screw tip (4). 35 Fig. 1
