A rivet head arrangement for a wobble or tumble riveting machine comprising a plurality of identical wobble rivet tools, the axes of which are in substantial parallelism with one another. A drive member is engaged by the head end of the wobble rivet tools, each such head end being remote from the effective or working end of these wobble rivet tools. The drive member is capable of transmitting to the wobble rivet tools a force directed towards their working ends. Further, a drive mechanism imparts to this drive member a translatory circular movement such that all of the wobble rivet tools carry out wobble movements, the centers of which are situated at their working ends. Also there is provided a support member upon which the wobble rivet tools at least are then supported by means of an intermediate portion when such wobble rivet tools do not bear upon the rivet ends to be deformed or formed.
