Description
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 decking boards to their 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 joists from view while still allowing efficient drainage.
 
Made of weather-resistant stainless steel to prevent rust, each fastener is 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.
