The tool comes with a spacer at either side, meaning there is a consistent gap between each deck board throughout your decking area. You can choose between a 1.6mm or 5mm gap with the switchable spacer, which is easy to change.
The screws go into the deck boards through the guides in the tool, which contains a stopper that stops the screw going in too deep! The system also enables that if you needed to replace a board, the screw heads easily can be removed without the need for the tool.
The range of fasteners mean that the screws can be used for treated or untreated wood, hardwood, composite, PVC, around swimming pools or the coast.
