Determine the values of the measured torque and the tightening torque for the screw in question. This information is available on the graph that you are working with. Both the measured and tightening torques will be represented on separate line graphs and will have a value between 0 and 2. Record the numbers that you find on the graph on a piece of paper.
Determine the value of "x" in the equation. "X" is determined by dividing the measured torque by the tightening torque. Use the values that you recorded in Step 1 to make this calculation.
Enter the value of "X" into the following equation: Tm(Measuring Torque)= X* Tt (Tightening Torque). In the case of this equation, "measured" and "measuring" torques will be different values. "Measured" torque was the number recorded in Step 1 and "Measuring" is the final value you are searching for. Enter in the tightening torque value found in Step 1 and multiply both values together. The answer that you receive is the torque for the screw in question.
