The shear screw (3) has a head (30) with a driver profile (33), and a threaded shaft with an outer thread (320), where the shear screw has a predetermined breaking point on the head or the threaded shaft. The end of the driver profile reaches to the area of the threaded shaft, in which the thread pitch of the external thread lies. A predetermined breaking point area (31) is formed, which is penetrated by the driver profile in longitudinal direction. An independent claim is included for a barrier post with an anchor plate. |
