I had a yellow handled Snap-On that matched my aerobatic plane. However,
needed the Modine heater in the hangar replaced one day, and after the work
the screwdriver was missing.

Still not convinced that an electric is the way to go- it seems like they
chew up the head more than a manual. In the operating room we use mostly
hex sockets or torx head screws. Of course, a single bone screw can cost
close to $100.

The key, like another poster said, is the use of a real low clutch setting.
Simply put, the clutch slips at such a low torque setting, that there is not
enough power to tear up a head. Loosen the first little bit, and tighten
the last bit to the correct torque with a hand driver.

Some screws, not requiring high torque, can still be done without using the
hand screwdriver.
