More About Millboard® Durafix Stainless Steel Screws
Millboard® Durafix screws are available in three sizes and are concealed fixings that simplify your Millboard® installation. The Durafix fixings can be used in two ways, either through the face of the boards or through the side using the DuoFix side-fixing guide tool.
Durafix fixings remain virtually hidden beneath the Lastane surface of boards, ensuring a near-flawless finish.
Use Durafix 35mm screws to securely fasten fascia boards onto recycled plastic or timber joists. Use 45mm screws to fasten Millboard® decking boards onto Cladco recycled plastic joists or DuoSpan beam subframes.
The Durafix 60mm screws are designed for fastening solid core decking boards to timber frames.
Please note: These screws are not compatible with hollow Cladco Signature composite decking boards.

The Lastane coating on Millboard® decking reforms over the screwheads, leaving minimal witness marks. Made from A2 stainless steel, these screws have a self-cutting tip, six-point torx head, and are waxed for easy use.
The DuoFix side-fixing guide tool offers an easy solution for fixing boards, leaving a clean hidden finish. When fixing through the face of solid decking boards, no pre-drilling or countersinking is needed; simply follow the relevant installation guide.
Each box includes a T15 hex shank drill bit. Use around 22 fixings per length for residential and 26 for commercial applications.
