6mm Hidden Fasteners



For fast, efficient and secure installation with no visible nails or screws, our 6mm Composite Decking Fasteners are a reliable and affordable option.

The plastic T-fasteners are designed to securely attach your deck boards to their frame, while reducing installation time and keeping costs low. Establishing a uniform 6mm space between each decking board, the fasteners create a neat and professional looking finish, with no fixings on display.

Attaching to the side of the deck boards, the concealed fixings are quick and easy to use, effectively holding the deck boards in place while allowing more natural movement than traditional timber joist screws.

Providing a clean and smooth finish, the fasteners remain hidden from view once secured in position, and the practical 6mm drainage gaps between boards left by the fasteners allow space for a drill or screwdriver for easy installation.

These affordable 6mm Composite Decking Fasteners are the go-to fastener for cost effective deck installations. For a premium finish with more closely aligned deck boards, 3mm fasteners are available.
