A drill can give you a lot of torque but the screw bit also functions
as a stripper. Once you slip on a drill the screw is history.

The solution is to use a long 1-foot screw driver with a hardened tip
with an exact fit. Our hands have the ability to sense that the screw is
about to strip, but a drill won't. The length of the screw driver will
give you a lot of precision and leverage. You will have to balance
your full weight on the screw driver. Don't tap or knock on the
distributor.
