Hello, I had for many years a torque wrench 70 – 210 N.m in which one turned the zero marking on the adjustment sleeve until it reached the lower edge of the corresponding N.m number on the key. Now I bought the above key and found that the lower edge of the marking is already reached at the number “16” on the sleeve and at the number “0” on the sleeve the cross stroke of the marking on the key is already somewhat below the edge of the adjustment sleeve In the adjustment sleeve there is an Imbus screw. Is it there to adjust the sleeve with the scale on the key? Greeting landbastler
