Practical Method for Adjusting Screwdrivers
Adjust the screwdriver to progressively increasing torque values until the screw breaks. Repeat the test on a certain number of pieces (sample batch) and determine the minimum torque value that causes breakage. Then adjust the screwdriver to a torque equal to 50-60% of this value.
