A torque screwdriver is a screwdriver with
components that ensure tightening to a specified
torque, ensuring tightening which is sufficient, but
not excessive. An insufficiently tightened screw
connection may loosen in operation, and excessive
tightening can damage parts
Torque screw checkers can be used to ensure that
the right amount of torque is being applied to your
assembly and repair processes.
Not only is it important to check the torque which
the screw driver is applying, It is equally important
to calibrate the torque screw drivers.
