Method for producing a securing arrangement and securing arrangement

A method for producing a fastening assembly (10) comprising a series of solid layers (12, 14, 16) that are in contact with one another and a screw (18), the screw (18) comprising a screw head (20) equipped with a driving point, a shaft (24) extending into a displacement tip (22), a thread (26) extending into the displacement tip and an unthreaded shaft portion (28) arranged between the thread (26) and the screw head (20), the method comprising the following steps:

• screwing the screw (18) into the series of solid layers (12, 14, 16), at least one of the layers (14) in the series of layers (12, 14, 16) that is furthest from the screw head (20) being deformed in a screw-in direction, so that a thickness Dp of the series of solid layers (12, 14, 16) is increased in a region directly around the screw (18) due to the deformation,
• continuing to screw in the screw (18) until the screw head (20) contacts and is supported on a flat surface of a first of the series of solid layers, a maximum thickness Dp, max of the series of solid layers being reached at this moment and a length LF of the unthreaded shaft portion (28) is up to 10% less than or up to 30% greater than the maximum thickness Dp, max of the series of solid layers.
