Screws for Solid Boards screws for the solid composite decking (and composite trim) are colour-matched to the board so that they integrate into the design and do not detract from the beauty. In order to ensure a flat surface with no protrusions, our screws have countersunk heads and small heads that sit flush with the decking surface. Saige screws are M4.5 x 65 carbon steel self-drilling screws high tensile screws which are heat treated and then de-embrittled, durable, long lasting and resistant to rust. Each box of screws will arrive with 1x star drive 50mm bit and 1x drill bit.
