Used this to loosen a couple of stainless steel M5 screws that our friendly neighbourhood boiler engineers had managed to cross thread and then tighten up beyond any sensible proportion. An electric impact driver had failed, as had plus-gas, heat, and a well fitting chrome vanadium screwdriver. A few taps with a hammer with this tool did the trick - screws loosened, and out they came, when nothing else had worked.
To those who don't know whether this tool will loosen or tighten - two things. 1) it's supplied in the 'loosen' setting, and 2) the easiest way to set it is to put it onto the screw you want to undo (or tighten) and then turn the body in the direction you want to move it in - this will set it correctly. Apply light turning pressure, and then hit it firmly with a hammer, and hey presto … out it will come. Be patient - a dozen firm taps is more effective than one large thud, which risks snapping the screw off..
Nice tool. The bits are good enough and appear to be CR-V.
