Offering the most pristine finish with the smallest gaps between boards, our hidden 3mm Composite Decking Fasteners closely align deck boards with no visible fixings.
Securely attaching your composite decking boards to their composite decking frame, the fasteners maintain a consistent minimal gap between boards for the ultimate neat and professional-looking finish, and the narrow gap left by the fasteners also conceals the aluminium joist or composite joist from view while still allowing efficient drainage.
Made of weather-resistant stainless steel to prevent rust, the decking clips are also black zinc coated for extra protection and reduced visibility and comes supplied with a durable weatherproof large head screw.
Each of our premium 3mm Composite Decking Fasteners is supplied with a fully threaded, large head self-drilling screw. Designed with a pointed tip to create its own pilot hole in the joist, the threaded screw eliminates the need for pre-drilled holes and effortlessly bores into the joist while tapping and fastening at the same time.
The large head offers greater resistance to penetration into the joist, and the weatherproof stainless steel screw has a black zinc coating that coordinates with the fastener and provides additional durability.

These were the best quality of all the decking clips/fasteners we tried. Well-made, and seem very strong and durable. Also, the price was very reasonable compared with others of inferior quality
I have given 5 star for decking service delivery all fantastic. The only thing I think could be improved on is bags of fixing an fastening only come in 100 bags way to many for order like mine so maybe doing bags with 50 in smaller orders .
These will no doubt sit in my shed for years such a waste .
Really great quality and easy to use, best when closed up a wee bit as this holds the board better. The screws work really well
So simple and easy to use.
I used these clips to secure my deck boards to the composite battens. Albeit a little fiddly at first I soon discovered a technique and motored on well. No visible fixing to the deck board and gave a very smart finish. I would deviantly use this product again.
