drive-adapter wrench)
Using a drive-adapter wrench (e.g., crowfoot wrench) in any position other than
90° and 270° to the frame of the torque wrench will affect the torque value
measured by the torque wrench because of the effective length (lever) of the
torque wrench changes. When using a torque wrench with a drive-adapter
wrench, multiply the listed torque recommendation by the calculated torque
conversion factor (
) to determine proper tightening torque. When using a
torque wrench with a drive-adapter wrench, the calculated torque will be lower
than the listed torque recommendation.
Example:
The measured effective length of the torque wrench (distance from
the center of the handle to the center of the square drive) is 457 mm (18 inches).
The measured effective length of the torque wrench with the drive-adapter
wrench installed (distance from the center of the handle to the center of the
drive-adapter wrench) is 483 mm (19 inches).
The calculated torque conversion factor for this torque wrench with this
drive-adapter wrench would be 18/19 = 0.947.
If the listed torque recommendation for a fastener is
103 to 127 N∙m (76 to 94
ft-lb)
, the proper torque when using this torque wrench with a drive-adapter
wrench would be
98 to 121 N∙m (72 to 89 ft-lb)
.
