Composite Decking Hidden Fastener Clips 6mm – 100 Pack

These composite decking clips offer a neat, hidden fixing solution for laying WPC deck boards, keeping your finished surface free from visible screws or fixings. Each T-shaped clip slots into the grooved edge of your decking boards and holds them securely in place while automatically maintaining a consistent 6mm gap between boards — which is exactly what you need to allow for natural expansion and drainage. The 7mm base depth makes them compatible with the vast majority of composite boards currently available on the market.

Made from durable plastic that resists corrosion, these clips are well suited to outdoor use where they'll be exposed to moisture and changing temperatures over the years. Because they sit hidden between the boards rather than on top, there's no risk of rust staining or surface damage, and the overall finish looks far cleaner and more professional than face-fixing with screws directly through the boards.

Each pack contains 100 clips and 100 black screws, giving you everything you need to get started without a separate trip to the hardware shop. They're a practical choice for anyone laying a new composite deck as a DIY project, and straightforward enough that even first-timers will find the installation process manageable. One pack will comfortably cover a modest decking area, though it's worth calculating your square meterage before ordering to make sure you have enough to complete the job in one go.
