Well, not exactly no screws but how about no screws that can be seen? I have viewed a couple YouTube deck builders who were making decks while screwing in from the sides.
Today I found the tool that can do this easily. It is called the Camo Marksman, from a company called Camo Fasteners. You place it over your board and it automatically spaces the board and allows you to screw in from the side.
The result is a very clean looking deck, love it.
