Applies to all chipboard screws.
Pozi drive is standard in Europe. Star (Torx) drive transmits more torque with less cam-out and is preferred for long timber screws.
Partial thread pulls two boards together; full thread is for fixing hardware and fittings into a single board.
A notched cutting point starts quickly near board edges and reduces splitting, which matters for decking and framing.
