Specifications

Which one do I need?

A 42mm drywall screw gives a bit more reach than the shorter lengths, which helps where the board is thicker or the frame behind is slightly out of line. For a single standard board on even studs, a shorter screw may be all you need. If in doubt, try one screw first and check the hold before fixing the rest.

How to use

1. Mark the stud or batten positions on the board.
2. Use a countersinking or depth-set bit so the head sits just below the surface.
3. Keep the board pressed against the frame as you drive each screw.
4. Avoid tearing the paper face, which weakens the hold.
5. Fill the heads and sand before painting.
