Calculation of Using Non-Standard Inserts
When using a torque wrench with an extended head (as shown in the figure below) will cause the applied torque to
be different from the actual required torque value. Therefore, the target torque value set on the wrench should be
calculated according to the following formula.

Instead of calculating torque with the formula each time, it is very convenient to use our unique Ratio function of
electronic torque wrenches. Enter the ratio K at one time, the actual torque value is displayed on the screen.
You can see some of the non-standard cases on Page 85.
