3/8" DRIVE SPLIT BEAM 20-100 FT. LBS.
FLEX HEAD TORQUE WRENCH
When using an extension or adapter
(increasing the effective length of the torque wrench)
the output torque value will change.
To calculate the new torque output of the wrench
use the following formula:
We calibrate each torque wrench at the factory using
torque standards according to DIN ISO 6789 & ASME
B107.300-2010, and certify it meets 4%+/- accuracy
and the requirements of specifications DIN ISO 6789
and ASME B107.300-2010.
A = Torque exerted at the end of adapter
L = Distance between square drive and hand position
B = Wrench scale reading
C = Length of adapter or extension
A number of variables including the length of the
adapter or extension, length of the wrench and
variations in hand position on the wrench will
affect the accuracy of the above calculation.
