F-5. CONVERSION FORMULA
Corrected dial or scale readings are determined by the use of the following formula:
Length of torque wrench+ Length of adapter
Required
Corrected
Length of torque wrench
torque value +
reading
=
NOTE
The length of the torque wrench is
measured from the center of the handle
to the center of the drive. The length of the
adapter is measured from the center of the
drive to the center of the wrench.
Example:
F5
CONVERSION FORMULA
In this example, the torque wrench measures 22 in. (55.9 cm) and the adapter is 3 in, (7.6 cm). The required
torque is 19 lb-ft (25.8 Nm).
19 lb-ft (25.8 Nm) + 22 in. (55.9 cm)+ 3 in. (7.6 cm)
Corrected
=
22 in. (55.9 cm)
