A beautiful timber deck should look like timber — not a grid of screw heads. At Bonum Home Improvement, we have been using hidden deck fastening systems for years because they create a cleaner, more refined finish while still providing secure fixing of the decking boards.
What is a hidden deck fastening system?
Traditional decking is often fixed by driving nails or screws vertically through the face of each board. Hidden fastening takes a different approach. With systems such as CAMO, specialised screws are driven through the edge of the decking board at an angle and into the joist below. Other decking products may use hidden clips with grooved boards. The important difference is simple: the fixing is concealed instead of sitting on the visible face of the deck.
Why we use CAMO hidden fasteners
We have built timber decks using this method for many years. The main reason we recommend it is the finished appearance. When the boards are installed correctly, your eye sees the natural timber grain and the straight board lines rather than hundreds of visible screw heads.
A cleaner, screw-free appearance
On a large deck, small details become very noticeable. Face-fixed screws create repeated dots along every joist line. Hidden edge fixing leaves the top surface visually uninterrupted, which can make hardwood decking look particularly clean and architectural.
No exposed fastener heads on the walking surface
Because the fasteners are installed through the board edges, there are no screw heads sitting across the main walking surface. This is one reason we like the system for entertaining areas, verandahs, balconies and other decks where the finish is a major part of the project.
Consistent spacing between decking boards
The CAMO installation system also helps the installer maintain consistent spacing between boards. Correct spacing is important for the appearance of the finished deck and for normal drainage and movement of timber. The exact installation method and spacing still need to suit the decking product being used.
Is hidden fastening suitable for every deck?
Not automatically. Timber species, board profile, board width, subframe condition, manufacturer requirements and the location of the deck all matter. Some boards are designed for edge screws, while some composite or grooved products use clip systems. There are also situations where conventional face fixing may still be the more appropriate construction method. We choose the fixing system to suit the actual deck rather than treating one method as universal.
The subframe still matters
An invisible fastening system does not compensate for a poor subframe. Joists need to be correctly positioned and the frame must be straight, stable and suitable for the selected decking. On replacement decks we regularly find that the work below the boards is just as important as the boards themselves.
Our experience with hidden-fastened decking in Melbourne
The photos in this article are from real Bonum Home Improvement projects. Over the years we have used concealed fastening on different timber decks, from smaller outdoor areas and balconies to large covered entertaining spaces. It is a detail we often recommend when the client wants the timber itself to be the visual feature.
