They are called Robertson screws, and are available in hardware stores
in the U.S., though the name may be different. I like them because
they don't cobble nearly as easily as Phillips screws.

The tool is easy: a screwdriver with a square end. You could take any
screwdriver and grind one in a few minutes.
