Abstract

A nut driver is provided in which a torque is delivered to a fastener while a bolt is rotationally maintained in a fixed position thereby tightening the fastener onto the bolt. The nut driver also removably attaches to pulse gun and includes a planetary gear arrangement. The nut driver is interchangeable with a variety of pulse guns. Although, conventional devices provide a torque to rotationally couple a nut to a bolt, the feature of interchangeability which allows utilization of different pulse guns is not available. The ability to interchange pulse guns allows the nut driver to easily be used with a variety of drive devices or pulse guns. Furthermore, the nut driver converts the variety of pulse guns into useful driving tools for fastening nut and bolts or other fastener pairs together.
