No Karl, never really suffer from broken screws to be honest (and that’s using B & Q cheapies as bulk purchases) nor have the need to remove deck-boards sympathetically. If a deck needs to come up, generally its old and needs replacing, so the boards can be beasted out if necessary.
I’d further suggest that the primary failure with screw heads is people not torqueing down their drills so as not to damage the head in the first place. By not over-torqueing the screw, the screw then sits at deck-board surface level rather than being driving into the wood which should mean it comes out easily? Coupled with an un-worn screwdriver bit of course set on slow speed for precision withdrawal rather than normal drill speed.
