Buying guide
Applies to all chipboard screws.
Drive type
Pozi drive is standard in Europe. Star (Torx) drive transmits more torque with less cam-out and is preferred for long timber screws.
Full or partial thread
Partial thread pulls two boards together; full thread is for fixing hardware and fittings into a single board.
Type 17 point
A notched cutting point starts quickly near board edges and reduces splitting, which matters for decking and framing.

Can you pack in retail boxes?
