SETTING THE TORQUE WRENCH
WITH TORQUE ADAPTERS
If a Torque Adapter is being used, the effective lever length will change with the addition of the
adapter. Use the equations below to compute the torque setting adjustment necessary.
NOTE:
Socket Drive Extensions are axially in line with the drive mechanism of the torque wrench
and do not require adjustments.
E
= Adapter length
L
= Torque wrench length
TW
= Torque set on wrench
TE
= Actual torque applied with extension in place
TW
= (TE x L) / (L+E)
TE
= (TW x (L+E))/ L
