Today we will test the Dewalt 12v DCF902B impact wrench rated at 2,400 in-lbs. or 200 ft-lbs of breakaway torque vs the Kobalt at 150 ft-lbs breakaway torque vs the Harbor Freight Hercules 100 ft-lbs. BreakAway Torque. We will be using the Loosening Torque Test. This test is also known as the “breakaway” test. This test uses force in the direction that loosens the fastener. To conduct this test, take a screw or bolt that is tightened down and begin to loosen it. When the fastener breaks loose, record the torque reading. The torque value to loosen the fastener is the approximate torque that was applied to the joint. This method is considered the easiest to perform, but it may not always correlate to the torque applied to the joint and at times the actual breakaway force required to remove the fastener can be up to 10% greater than the force required for tightening.
