Abstract
A locking block screw connection provides material-elastic protection against loosening of the screw by a novel configuration of the connection zone, where a bore and a screw are engaged. The bore is provided with a circular taper at the thread runout. The screw has a pin continuation where an annular groove is provided. When the screw is screwed into the bore, the taper of the bore is elastically deformed until the taper engages in the groove of the screw. The engagement between the taper and the groove provides an axial security against loosening of the screw.
