For emergency use, it'll do, and probably without a NOTICEABLE
amount of damage.
But for a Torx screw, there is no such thing as a
"peroperly fitting flat-head screwdriver".
'course with a little bit of careful grinding on the corners
of the screwdriver, you could make in into a properly fitting
"two-point" Torx driver.
Or decide how much minor damage/wear you are willing to inflict
on fasteners by utilizing a tool that is not quite right.
