This worked perfectly for me and was incredibly less expensive than a torque wrench with the same capability would have been. The multiplier has a range of accuracy of something like 4% which has to be figured along with the accuracy of the torque wrench you're using as well. This could result in a relatively large variance in actual torque applied but that's the payoff for saving a couple hundred dollars (minimum) on a higher capacity torque wrench. ## Features - 💎*Energy-Saving Tool for Tire Change* -- Input square: 1/2" ; Output square: 1/2".
