Torque is the measure of twisting force. The length of the handle has nothing to do with it other than the fact that whatever the length is you have to multiple the torque by the handle length. (Boy I didn't even understand what I wrote) So for example there are very few people in the world that can reach down with their hands and turn a nut to 100 ft-lb, however, if you take 100 and divide it by 2 (a 2 foot handle) you get 50. Now most people can grab onto a two foot handle and pull 50 pounds. Now granted most torque wrenches are 18" long but I used 2 feet long for simplicity. Now depending on what inch pounds you need, if it is a little bit high, you can still use a foot pound wrench, just multiply or divide by 12. So 12 inch pounds equals 1 foot pound. So divide your inch pounds by 12 and viola...how do you spell viala...anyway there you have it. Well sorry you now have more info than you wanted so Sears, Craftsman, Part number 44560, Price $59.99.
