ABSTRACT:
A fastening tool draws a mandrel (5) to allow a caulking portion of the mandrel to deform a stem of a rivet (2) so that workpieces are fastened together. The fastening tool used in this process includes a nosepiece having a protrusion. During caulking, the protrusion of the nosepiece applies a force on a flange of the rivet to form a recess in the rivet flange and thereby peel a coating of the workpieces. As a result, electrical conductivity between the workpieces and the rivet is obtained.
