ABSTRACT:
A blind rivet setting tool for setting threaded rivet nuts comprises a threaded pin for engaging the rivet, and a rotating mechanism to screw the nut on to the threaded pin before a rivet upsetting operation, and to unscrew the pin from the nut after the upsetting operation. The upsetting operation is performed by imparting an axial movement to the pin. The rotating means is actuated to screw the pin into the nut by applying an axial pressure to the tool and the pin while, when the axial load on the tool is relieved, the rotating mechanism automatically rotates the pin in the opposite direction, for disengagement of the pin from the rivet.
