Refer to the illustration and formula below when calculating the proper adjusted values for
wrench torque, wrench force and bolt torque.
NOTE: If the Torque wrench setting at length “2” would be 720 ft.lbs. (976 NM) for
capscrews not requiring us of adapter, then the following shows the use of an
adapter and the calculation for that setting.
FORMULA
Torque wrench setting (TWS) = (720 ft-lbs.) times ("2")
-----------------------------------
("2") plus ("1")
=lpq-Plw
EXAMPLE
1 = 10.25"
2 = 43"
TWS =(720 ft.lbs.) X 43
-------------------------
43 + 10.25
= 30960
-----------
53.25
= 791 ft-lbs.
