Torque Adapter Snap-on FRDHM13 (Re-worked)

Special Tool Notes
1. Special Tool Notes
The depth of the adapter ring end must be reduced to approximately 6.0 mm. An allowance for the increase in leverage must be made when using the adapter.
2. Torque wrench setting using may be achieved using one of the following methods:
Torque wrench calibration machine; apply the specified torque at the calibrator (using the adapter) and note the corresponding reading at the torque wrench Formula to calculate the effect of the added length
RS = (W x T) / (W + L)
Where
RS = Torque wrench setting
W = Effective length of the torque wrench
T = Torque specification
L = Length of adapter

Example
1. Using a torque wrench 330 mm (0.33 m) long and an adapter 50 mm (0.05 m) long, calculate as follows for a specified torque of 60 Nm:
RS = (0,33 x 60) / (0,33 + 0,05) = 52,1 Nm
