Aug 20, 2016 at 18:48 comment added U2791227 The particular torque wrench I have (pictured) can only be used to tighten a right hand thread. To use it for any other purpose would put it out of calibration or damage it. The tool's maker specifically warns of that. I agree, the dial type beam wrenches are bi-directional, but that isn't what I was referring to. At any rate, a breaker bar is a far more appropriate tool to loosen nuts with.
Jul 7, 2016 at 8:50 comment added I have no idea what I'm doing @Ellesedil some bolts are reverse threaded, sometimes the torque wrench is the closest tool with a long elbow. It doesn't really matter, the question is theoretical, why not use it in reverse if it has a scale on there?

Jul 5, 2016 at 19:14 comment added TMN @Ellesedil: Sometimes you want to measure breakaway torque. This can tell you if a fastener has started to loosen due to vibration, or was over-torqued and the bolt/stud may have stretched or weakened. It can also show that someone used an impact gun instead of a torque wrench to install your lug nuts.
Jul 5, 2016 at 19:00 comment added Ellesedil @IhavenoideawhatI'mdoing: Is there a reason why you'd want to use a torque wrench specifically in order to loosen a bolt? I can't think of one; I'd rather loosen the bolt and then re-tighten with the torque wrench.
Jun 13, 2016 at 7:34 comment added I have no idea what I'm doing Interesting, why's that? Some "deflecting beam" wrenches are "dual", why would it hurt the wrench to use the other side of the scale? use-enco.com/ProductImages/0045383-24.jpg
