You place the Back-Up Wrench on the counter-nut, tighten the nut with a torque wrench and then take off the Back-Up Wrench from the counter-nut, very simply and safely. As the Back-Up Wrench releases so easily, there is no need for a hammer. The speed of work will increase rapidly in comparison to a slogging wrench. When tightening the nut, you can keep your hands away from the backup wrench and the tool, so that they cannot get pinched.
