Standard Torque Wrench
(actual torque required) X (torque wrench length)
(torque wrench length) + (length of adaptor)
EXAMPLE:
100 Ft-Lb (136 N•m) x 1 ft (308.4 mm)
1 ft (308.4 mm) + 0.75 ft (228.6 mm)
The correction shown is for an adapter that is aligned with the centerline of the
torque wrench. If the adapter is angled 90 degrees relative to the torque wrench
centerline, the torque wrench reading and actual torque applied will be equal.
