“Break-Over” wrenches are essential
to limiting the amount of torque applied to an assembly or fastening. Upon reaching the preset torque value, the tool “breaks” at a specific point along the tool’s length - usually at a pivot point near the tool’s head. It typically deflects 20 degree or 90 degree on torque delivery; thus indicating torque has been reached. Continuing force after the break will increase the torque applied above the preset value. Many break-over wrenches require manual resetting, while others have an automatic
resetting feature.
There are three styles in which the wrench can signal achieving torque, either by a “click,” “break,” or “slip.” Each of three wrench styles has a specific purpose and utility. When you decide to spend the money for one, it’s important that you select the one that will do the job properly and not generically.
