Abstract: The invention relates to a method and a device for fastening a rivet nut (2) on a workpiece (3), in which a hole (5) is punched into this workpiece and the rivet nut (2) is introduced into this hole by its section (14) to be riveted, after which the rivet nut (2) is riveted to the workpiece (3) by means of a riveting tool. To make it possible for the rivet nut (2) to be fastened on a workpiece (3) in a simple and problem-free manner, it is proposed that, after the hole (5) has been punched, the workpiece (3) is fed to a first follow-on tool (13) in which the rivet nut (2) is introduced into the hole (5) by its section (14) to be riveted, the rivet nut (2) in the follow-on tool (13) being aligned with a discharge channel (19) which is arranged in the first follow-on tool (13) below the workpiece (3) and whose diameter is at least as large as the maximum diameter of the rivet nut (2). The rivet nut (2) now inserted in the hole (5) is then riveted in a second follow-on tool (21) designed as a riveting tool.
