For producing coupling members with a negative relief of the load-bearing contact surfaces, according to a method for the precision forging of coupling members, it is proposed that in a rough-forging process, first of all contact surfaces (5) parallel to the direction of the forging stroke are produced and in particular with an admeasurement exceeding the adjoining top faces (2) at least in the marginal region adjoining the respective common edge (3) of the spacers and that in a subsequent cold gauging process, the top faces are forged with exact measurements so that every finished contact surface extends obliquely towards the top face enlarged by gauging.
