A contact device for establishing an electrical connection to a contact point of a printed circuit board is insertable into a contact hole arranged at the contact point, so as to establish an electrical connection to the contact point of the printed circuit board. The contact device includes a contact element having a deformation portion and a screw element operable to be screwed into the contact element. The deformation portion is in a longitudinal extension state when in a pre-assembly state and is operable to be deformed out of the longitudinal extension state when in an assembled state by means of the screw element being screwed at least part way into the contact element.
