Torque Screwdrivers
Why to use screwdrivers with torque sensing/limiting function
The torque limiting screwdriver is an ideal tool to protect the screw head (and the tool itself, of course).
The tightening or loosening with an unadequate torque can damage the screw head and the screw cannot be loosened/tightened again.
Buying the torque screwdriver
When buying the torque screwdriver, choose one that is light-weight and has comfort handle with lip resistant surface, if it has exchangeable bits, then buy also
the bit set
from the same manufacturer.

The screwdriver bits as well as its shaft should be produced from the high-grade steel, the bit holder should release the bits easily and the torqe sensing mechanism should also have a locking collar.
The power torque screwdrivers
Almost all power screwdrivers have an automatic shut-off clutch to avoid the over tightening. To get in all places I would recommend to buy a
power torque screwdriver with articulating head
and - alternatively -
a site light
for better comfort.
