Abstract: A tool for loosening or tightening vehicle wheels nuts using a multiplying torque. At one end of the main body there is a rotating shaft the other end sits on the ground to create a resistance platform. The rotating shaft has a nut socket on its end, which engages onto one of the wheel nuts.
