3mm Hidden Fasteners



Offering the most pristine finish with the smallest gaps between boards, our hidden 3mm Composite Decking Fasteners are the best fasteners to use for a premium finish, closely aligning deck boards with no visible fixings.

Securely attaching your decking boards to their frame to create a solid and stable surface, the fasteners reduce alignment time during fitting as they act as a built in spacer, maintaining a consistent 3mm gap between the boards for the ultimate neat and professional looking finish.

Quick and easy to use, the concealed fixings effectively hold the deck in place without being intrusive, and offer a cleaner finish than traditional timber joist screws. 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.

Creating a seamless finish, the fasteners remain hidden from view once secured in position, and the narrow 3mm gap left by the fasteners also conceals the joists from view while still allowing efficient drainage.
