Self-aligning screw thread?

The 4th is a self tapping machine screw that has a tapered thread and
slits cut in it to take away the waste material just like a tap.
Those are my least favorite. Unlike a tap where you sometimes turn it
backwards to break the chip or even remove it entirely to clean the
grooves most of those are rammed in with little thought to removing them.
