How to hide screws in a wooden deck?

[Chris Bacon]

(etc, etc). I haven't seen stuff reeded both sides, but it does exist as in the link. Wouldn't have it myself, I think it looks horrible.

[nothanks]

Have the holes been plugged

or simply driven into the board using an impact driver?

In my experience decking planks are pretty ?soft? and if a screw is well driven in below the surface, the wood fibres will spring back to almost totally conceal the screw head.
