They work on a torsion theory, which is just a fancy way of saying they flex at a certain rate, then stop applying torque when they reach a specified flex point. As far as I can tell they are designed to twist along their long axis. ~~This can be useful when you want to apply a lot of torque to a nut in order to bust it loose, but you dont want to strip or damage the nut.~~ The torque stick will twist before the nut deforms but still transfer the energy to the nut in order to ~~bust it loose~~ Please correct me if I have misunderstood this Edit: as stated below they aren’t used to loosen anything. They allow you to tighten nuts to a specific level 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
