CONVERSION FORMULA
Corrected dial or scale readings are determined by the use of the following formula:
Corrected
Required
Length of torque wrench + Length of adapter
=
reading
torque value
Length of torque wrench
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:
LENGTH OF
TORQUE WRENCH
22 IN. (55.9 CM)
LENGTH OF
ADAPTER
3 IN. (7.6 CM)
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).
Corrected
19 lb-ft (25.8 Nm)
22 in. (55.9 cm) + 3 in. (7.6 cm)
=
reading
22 in. (55.9 cm)
