Torque Wrench Chart

Torque Wrench Chart - Web these metric bolt torque charts show the ideal tightening torque for class 8.8, 10.9, and 12.9 bolts for both wet and dry tightening. The audible and tactile clicks on reaching the scale values also facilitate the safe setting of the desired torque value. Imperial has made a concerted effort to provide accurate information in its catalog and on its web site, however imperial assumes no responsibility for the accuracy of the information. These can be found in the owner’s manual or online. Cdi comfort grip micrometer adjustable torque wrench. The selection of optimal drive size is largely dependent on the sockets the user owns, the most common fastener sizes to be turned and the operating torque value (s) most commonly worked within. 1) the torque values can only be achieved if nut or tapped hole has a proof load greater than or equal to the bolt’s minimum tensile strength. The bolt’s class indicates its material strength, with higher numbers meaning higher tensile and yield strength. Testing the calibration of the torque wrench. Measure from the square drive to the handle.
