The present invention provides a tool for converting axial force into torque comprising a body and set teeth positioned on the body. The tool also has a mandrel positioned to move relative to the body and drive teeth positioned on the mandrel such that there is relative motion between said set teeth and said drive teeth. When the set teeth and drive teeth engage, torque is applied to the mandrel.
