FQAs
How do you use a preset torque wrench?
To use a preset torque wrench, first determine the correct torque value and adjust
the wrench to the desired value by turning the handle or knob until the scale aligns
with the required torque setting. Then, attach the appropriate socket or bit to the
wrench and tighten the fastener until you hear or feel a click, indicating that the
pre-set torque has been reached. If multiple fasteners need to be tightened to the
same torque value, ensure that the wrench is reset to the appropriate setting before each use.
What is the difference between a preset and adjustable torque wrench?
The main difference between preset and adjustable torque wrenches is that preset
wrenches have a fixed torque setting that cannot be adjusted by the user, while
adjustable wrenches allow the user to adjust the torque setting within a specified range.
Preset wrenches are simpler to use and less expensive than adjustable ones.
However, adjustable wrenches offer more flexibility for a wide range of applications
that require different torque values, and they require more careful adjustment to
ensure the correct torque value is achieved.
