ABSTRACT:
A system for installing an elongate fastener which is partially threaded in a workpiece is provided. The system includes a mass which is resiliently mounted so that it is reciprocatable at a resonant frequency. The mass is excited so that it reciprocates at least near its resonant frequency. A chuck is provided with a front portion adapted to releaseably support the fastener, and a back striking surface. The chuck is located so that the reciprocating mass intermittently impacts the striking surface of the chuck to drive the fastener into the workpiece until the threaded portion of the fastener engages the workpiece. Once the threaded portion of the fastener engages the workpiece, the front portion of the chuck is rotated to correspondingly rotate the fastener to complete the installation of the fastener in the workpiece.
