The process 'automatic screw driving' is one of the most difficult and at the same time very spread because of the advantages of the threaded joints. A basic characteristic feature of the precision of the assembly process according to the classical understandings is the error in the relative disposition of the parts at the moment, right before starting the assembly-the d isplacement of the axes of the screw and the hole, as well as the angle of the screw grad ient in relation to the hole.

The results from the carried out works on a specialized device are g iven. The got experimental data are analy zed by a statistics program.
