Dear Experts,
You know those special screwdriver bits for plasterboard - a PH2 point with a sort of collar around it. What’s the idea?
Possibilities:
- The collar is supposed to retain the screw somewhat while you wrangle the board with one arm and wave the drill with the other.
- The collar prevents the screw from driving too far into the plasterboard.
- The collar indents the board slightly giving a sort of countersink.
In my experience they seem to do all of those things to some extent, though I’m often still left with screws that are a tiny bit proud (I presume that they need to be fractionally below the surface for skimming).
Thoughts?
