Can you use a torque wrench to Untighten?

You certainly could use a torque wrench to loosen bolts, it is not the best idea. Torque wrenches are precision measuring instruments, using them to loosen bolts is not in line with that purpose. You end up stressing the tool when it is used as a breaker bar, and you often need excessive force to loosen bolts.

What is the best wrench to use to loosen a bolt?

For example, a box-end wrench is a good option for loosening stuck fasteners because you can apply more torque without risking damage to a ratchet mechanism. A wrench with an open end fits around a fastener instead of over it, so you can slip it into an area where there isn’t room for a socket.

Is it better to pull a wrench to tighten or loosen a bolt?

Always pull, rather than push, a wrench for greater control and balance. That way, if the nut or bolt should suddenly loosen, you’re less likely to go flying. Never try to get more torque from a wrench by using a cheater bar or other device to extend the leverage.

What happens if you use a torque wrench as a breaker bar?

Never use your torque wrench as a breaker bar—that’ll damage the torque mechanism. Carry it with kid gloves—a single fall can knock the accuracy off by as much as 30 percent. If you do drop it, get it recalibrated (calibration firms listed below) before using it again.

Can I use a torque wrench as a regular wrench?

No. A socket wrench is a specific type of wrench using interchangeable sockets to drive the nuts or bolts. A torque wrench is a special version of the socket wrench that has means to set or limit a specific amount of torque measured in ft-pounds or newton meters to the bolt fastening.
