A wrench is a wrench; hence it can be used both for fastening and for loosening bolts and nuts and other similar hardware. This is the logic shared by many torque wrench users. While torque wrenches can be used for undoing, care must be taken not to apply more torque than the wrench’s maximum torque.Click to see full answer. Besides, can you damage a torque wrench to loosen bolts?So long as users operate with caution and do not exceed the maximum torque, most torque wrenches can be used for undoing. By exceeding the maximum torque limit during a bolt loosening you can affect the wrench accuracy, causing problems for future use. If in any doubt, use another tool for loosening bolts.Furthermore, can you use a torque wrench as a ratchet? Torque wrenches can be used on any bolt that needs to be tightened to a specific setting. Because torque wrenches do not have a ratcheting mechanism, a ratchet is usually used to tighten the bolt. The torque wrench is then used to apply the final torque setting. Hereof, how much torque does it take to loosen lug nuts? Generally speaking, you should torque lug nuts of your car wheels from 80 to 100lb-ft. This is tight enough to keep them from coming off, but not so tight that an impact driver cannot remove them.Do torque wrenches need calibrated?However, torque wrenches need to be calibrated regularly to make sure they’re giving accurate readings. While it may be best to take your torque wrench to a professional for calibrations, you can do a pretty good job of keeping your torque wrench accurate by calibrating it at home.
