A method of producing fastening assembly () including a series of layers () and a screw (), the screw () having a screw head (), a shaft (), a thread () extending into a displacement tip () and an unthreaded shaft portion (). The method includes screwing the screw () into the series of layers (), the layer () in the series of layers () that is furthest from the screw head () being deformed in the screw-in direction, so that a thickness Dof the series of layers () is increased in a region around the screw (), and continuing to screw in the screw () until the screw head () strikes the series of layers, a maximum thickness Dof the series of layers being reached at this moment and the length Lof the unthreaded shaft portion () being up to 10% less than and up to 30% greater than the maximum thickness Dof the series of layers.
