SCREW, FASTENING ARRANGEMENT AND USE OF A SCREW
A screw (10) having a screw head (14) equipped with an engagement portion (12), having a shaft (16) which defines a screw axis and which bears a thread (18), and having a thread-free shaft portion (20) arranged between the thread (18) and the screw head (14). A head-side end (22) of the thread (18) is truncated. Additionally, the thread (18) ends, adjacent to the thread-free shaft portion (20), in an end plane (32) which, with a constant spacing to the screw head (14), runs at least partially around the shank (16) and forms an angle αE with the screw axis, and a head-side flank (34) of the thread (18) averted from the thread-free shank section (20) forms an angle αF with the screw axis, and the angle αE is smaller than the angle αF.
