The present invention relates to a weld-on fastener for an electrical contact with a weld nut ( 1 ) which, on its topside has an electric contact face ( 9 ) and, on its bottom side, has an annular axial projection ( 6 ) which surrounds a cavity ( 4 ) of a pre-determinable depth (T), and with a screw ( 3 ) screwed into the weld nut ( 1 ), which screw ( 3 ) also has an electric contact face ( 9 ), a spacer ring ( 2 ) being clamped between the contact faces ( 9 ). The spacer ring ( 2 ) preferably has a thickness (D) which is approximately equal to the depth (T) of the cavity ( 4 ). When the spacer ring ( 2 ) is clamped in, the screw ( 3 ) ends approximately flush with the end of the internal thread ( 12 ) of the weld nut ( 1 ). This combination is distinctive in that it has only a low overall height, no metal scabs reach the thread ( 12 ) during welding-on, the contact faces ( 9 ) are protected during assembly and the welded connection can absorb high torques even when welding onto thin work pieces ( 7 ).
