Torque Wrench Info.
Just a little useless info to thoroughly confuse everyone, most click type torque wrenches are accurate to 4% clockwise and 6% counterclockwise within the range of 20% of full scale to 100% of full scale. That is to say a 200 inch pound max setting wrench set to say 50 inch pounds and used in the CW direction should yield a torque accuracy of 48-52 inch pounds. This will be true as long as the unit has been properly calibrated. It is also true that leaving the adjustment barrel turned up to a high setting for a lengthly time will weaken the spring inside the wrench, once weakened it will not return to original length and may become uncalibratable unless repaired. So turn those click type torque wrenches to the lowest setting on the barrel when finished using. Most dial type torque wrenches will produce a higher accuracy with these units coming in at 1% or 2% of reading from 20% to 100% of FS both CW and CCW directions and you won't have to turn them down after use. I have calibrated many brands and types of torque devices and have found most major brands to be very good, Snap-On, MAC, CDI, Craftsman, Stanley-Proto, Sturtevant Richmont to name a few. For best accuracy a torque device needs to be exercised before using (make it click or make the dial pointer move several cycles by holding the square drive stationary).
