Multi-tier torque enhancer driver and/or receiver and method of using same

Abstract

A torque enhancing device that includes a torque contact body having one or more torque driver and/or recessed recipient torque contact surface configurations, inclusive of those in a multi-tier arrangement. The body having a Z-axis depth or thickness, and each of the torque contact surface configurations includes a pair of X-axis extending torque contact side walls that are spaced apart by Lalong a Y-axis, and a pair of Y-axis extending torque contact side walls that are spaced apart by Lalong the X-axis, with at least one of the one or more torque contact surface configurations having four concave contoured surface portions positioned between respective adjacent most ends of the X-axis extending torque contact side walls and the Y-axis extending torque contact side walls, and a length ratio L/Lis less than 1 as to provide a torque enhancement contact surface configuration. A method of driving such as insertion or removal of the recessed recipient such as in fastener form is included.
