HardieBacker screws for floors, for walls, for metal frames
Self-countersinking, they cut a shaped hole in the fibre cement backer board, so that as the screw is tightened the head finishes flush with the surface of the board.
Extra strength screws ensure our impervious and strongest-on-the-market cement board stays fixed, with the power to hold up to 100 kg/m².
Make sure your substrate fits perfectly and stays fixed – with clean-cut edges that align tightly when you use our purpose-made tools and accessories.

For wood frames (walls) use: 4.0 x 32 mm, diameter head 10 mm PZ2
