Maybe I'm mis-reading these posts , but IIRC , adding length to the HANDLE of a torque wrench will NOT make any difference to the torque readings the wrench gives you , it will just add leverage & make it easier on your arms to reach the desired torque . The torque at the head of the wrench , is the torque at the head of the wrench whether the handle is 6 inches or 60 inches . Adding an extension to your socket , however , WILL change the torque reading . A 3" extension will not change the reading much at all , but a long extension will change it much more .
