Hidden Fasteners - 3mm (Bag 100)

Our 3mm composite decking fasteners provide a superb finish; allowing for minimal gaps between boards for a clean professional finish with no visible fixings, yet still allowing for adequate drainage.

These fixings are made from 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 fastener is supplied with a fully threaded, large head self-drilling screw which has 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.
