When using universal joint drives, it is recommended that a new effective torque is determined (see below) The use of adapters or special plug-in tools alters the effective length of the wrench compared to the„normal" drive take-off point, which changes the effective torque setting. The new torque can be calculated as follows: TE= TS X (L + A) L TS = TExL (L + A) TE = Effective torque at the adaptor drive point. L = Distance between centre of grip and„normal" drive point A = Length of the adaptor. TS = Torque setting at the scale. 657940 542
