Millboard Facia Screws 35mm x 4.5mm (100)

Our decking system is complemented by our unique Durafix screws. These hidden fixings make installing Millboard straightforward.

DuoFix provides a quick and easy fixing solution, leaving a clean, hidden fixing finish. When fixing through the face of the boards there’s no need to pre-drill, countersink or use clip fixings, simply fix the boards in accordance with our installation guide. Once the screws have been applied, the innovative Lastane coating on the board flexes back over the screw-heads, leaving a minimal witness mark.

Made from A2 stainless steel, the screws have a self-cutting tip, six-point torx head, and are waxed for ease of use.

Each box also includes a T15 hexshank drill bit. You will need around 22 fixings for each length of Millboard decking for residential applications and 26 fixings for commercial applications. 

For installing fascia or Envello cladding boards onto battens that have a thickness of 25mm or greater, these fixings should not be used for installing decking boards.
