What is a backup wrench?
During tool operation, a backup wrench gets placed on a passive, non-torquing nut. A backup wrench will prevent the rotation of the passive nut when the active nut is tightening. There is no need to hold the HYTORC magnetic backup wrench during tightening, which improves the safety and speed of your bolting job.
