A torque wrench is a wrench with a scale, click mechanism or display that allows a screw to be tightened to the specified torque.
What it is for
Used in mechanical maintenance of machinery and plant, during scheduled shutdowns or breakdowns, for vehicle maintenance, in the workshop and on the road and for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Set the torque specified by the manufacturer, fit the socket fully and pull slowly until the wrench clicks or the display shows the value; at that point, stop pulling. Do not use it for loosening or as a lever. After use, on click-type models, return the setting to the minimum; store it in its case and have its calibration checked periodically.
