  • Installation tool for deformable head fasteners
    Patent number: 6427514
    Abstract: A drill mounted tool for installing collapsible deformable head fasteners includes a yoke supported on the drill housing carrying a reciprocal nosepiece rotatably coupled at a left hand threaded connection to an actuator shaft connected to the drill chuck. The actuator shaft has an external projecting right hand threaded end for carrying the fastener. Upon drill actuation, the actuator shaft extends the nosepiece relative to the actuator shaft thereby collapsing and deforming the fastener into secure engagement with a workpiece.
