Torque Wrench Facts

 

Torque Wrench Usage

• All mechanical torque wrenches are calibrated from 20% to 100% of full scale, therefore, they
should never be used below or above those limits
• To determine which torque wrench capacity is best suited for an application, many factors must
be considered. However, as a recommendation, use a torque wrench in the middle 50% of the
overall capacity of the tool. This will result in longer tool life, ease of use for the operator and
increased accuracy from “clicker” type torque wrenches
• Always grasp handle fi rmly in the center of the grip
• Approach fi nal torque slowly and evenly
• Stop pulling wrench immediately when target torque is reached
• Never use a torque wrench to break fasteners loose
• Should be cleaned and stored properly
• Should always be stored at it’s lowest torque setting
• Wrenches should be re-calibrated if dropped. Should never be used in excess of it’s capacity
• Torque wrenches should be “exercised” a minimum of three times at 100% of full scale before
use
• The wrench selected should be calibrated in the same torque units that are specifi ed
• Use of a “cheater bar” will result in an inaccurate reading and can possibly damage the wrench
• Torque wrenches will last longer if reasonable care is taken. Always unwind handle to the lowest
setting after each use. Do not attempt to lubricate the internal torque mechanism. Clean torque
wrench by wiping, do not immerse. The wrench should be sent to a qualifi ed calibration lab once
every year or every 5000 cycles for re-calibration
