Torque Wrenches
MADE IN USA
USE OF ADAPTORS, EXTENSIONS AND UNIVERSALS
Anytime an adaptor, extension or universal is used with a torque wrench in such a way that the fastener distance is different than the torque
wrench square drive distance, an adjustment to the set torque is required to get proper fastener torque.
Fastener torque equals torque wrench square drive torque.
Wrench setting is equal to desired fastener torque.
Fastener torque equals torque wrench square drive torque.
Wrench setting is equal to desired fastener torque.
When using wobble extension or a universal, do not exceed more
than 15 degrees of offset from perpendicular drive. Do not use a long
extension with the flex-drive at full flex.
Fastener torque is greater than torque wrench square drive torque.
Calculated setting will be lower than desired fastener torque.
