When using the DuoFix Side-Fixing Guide to align Durafix® screws into the side of our boards, the DuoFix Driver Bit is essential. As well as the complimentary DuoFix Driver Bit that comes packaged with the DuoFix Side-Fixing Guide the DuoFix Spare Driver Bit Kit is now available to purchase.

Each kit contains 2 Driver Bits, 4 Nylon Washers and 4 Stainless Steel Washers. Please note that driver bits wear over time, and we expect each of our driver bits to last up to 1000 uses.

Our quick & easy fixing solution for a clean finish

Our innovative tool provides a quick and easy solution to fix the boards from the side, resulting in a clean, hidden fixing finish, keeping the face of the board clear of screw holes. This quality gives a clean look, even when used with lighter coloured boards.

To use, the Guide simply lays over the decking board and is adjustable to board widths of 145-200mm, making it compatible with all Millboard decking boards, and even some softwood decking boards. When used in combination with Durafix® screws and the complimentary driver bit, the Guide aligns the screws perfectly and controls the fixing depth too, providing a 6mm spacing between boards.
