1. An assembly method for screwing a screw into an internal thread of a medical instrument in order to connect two branches of the medical instrument to each other such that the two branches are pivotable relative to each other, using a screwdriving tool, the assembly method comprising the steps of:
imprinting a punch geometry into a screw head of the screw by applying an axial compression force to the screw using the screwdriving tool; and
rotating the screwdriving tool relative to the medical instrument about a longitudinal screw axis to transmit torque from the screwdriving tool in a form-fitting manner via the punch geometry to the screw and to screw the screw into the internal thread.
