Place the Back-Up Wrench on the counter-nut, then tighten the nut with a torque wrench. When torqueing is complete, remove the Back-Up Wrench from the counter-nut. Removal of the Back-Up Wrench does not require the use of a hammer, making removal very easy and much safer than other methods. Speed of work will also increase significantly when compared to removal methods using a hammer and slogging wrench. Using our Back-Up Wrench also makes the torqueing process Hands-Free, eliminating possible pinch points.
