I am about to fix a small brass plate to the front door. The door is
black, with brass door furniture, so it should look OK (after I've
cleaned the rest of the brass!)

I'd like to use some brass screws, but wondered about security screws in
case some scrote decides to nick it (not sure how likely this is, though).

Can you get brass security screws, or are they too soft to work? Even
Torx or Torx+pin would be good; I don't really want the 'one way' ones.
