virden Posted October 1, 2013 Share Posted October 1, 2013 Numpty question: If I use an extension bar beteeen the wrench and the socket does that increase the leverage and therefore understate the true torque applied? If so is there a constant to be applied to the reading? Link to comment Share on other sites More sharing options...
charlie_pank Posted October 1, 2013 Share Posted October 1, 2013 Using an extension bar makes it easier for you to apply more torque, but the wrench still clicks at the right torque. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted October 1, 2013 Share Posted October 1, 2013 I think Virden is referring to a socket extension rather than tube on the handle extension in order to increase the reach of the socket. Link to comment Share on other sites More sharing options...
Roger Ford Posted October 1, 2013 Share Posted October 1, 2013 You mean an extension bar like this? http://uk.farnell.com/productimages/farnell/standard/42345511.jpg No, it won't make any difference to the torque at all. Link to comment Share on other sites More sharing options...

oilyhands Posted October 1, 2013 Share Posted October 1, 2013 Just make sure the extension bar is perpendicular and that you don't hold the extension as you apply the torque. Oily Link to comment Share on other sites More sharing options...
