A nut-plate riveter (10, 10a) which includes multiple pistons (18, 20, 20a) which assist in creating a pulling force. The nut-plate riveter (10, 10a) provides that spent mandrels (22) are pulled through the tool, thereby avoiding problems in the field. The nut-plate riveter (10, 10a) includes a handle (12) and a plurality of pistons (18, 20, 20a) disposed in the handle (12). Cavities are proximate the pistons for pressurizing the pistons (18, 2 0, 20a), and air supply passages are in communication with the cavities for supplying air to the cavities to pressurize the pistons (18, 20, 20a). A piston rod (80) is engaged with at least one of the pistons (18), and the piston rod (80) has a longitudinal bore (88) therethrough which is configure d to receive a spent mandrel (22). A deflector fitting (34) may be disposed at an end of the nut-plate riveter (10, 10a). |
