How do the pros do this? *Is there a drill bit for one-way screws? *I also

Any suggestions would be very much appreciated.

Not having security screws I filled the slots of regular screw with
epoxy after they were tighten down the painted them with black paint.
If I ever need to remove thm the epoxy can be cleaned out with out an
undue amount of trouble. Otherwise they look like carriage bolts or
rivets and people leave it along thinking its just too much trouble to
break into. As far as security bolts go there is a tool for removing
just about all of them that can be easily purchased by just about
anyone.
