6mm Plastic Hidden Decking Fasteners – Bag of 100

Create a clean, screw-free decking finish with consistent 6mm spacing.

These 6mm plastic hidden fasteners are designed to fit neatly into the side groove of composite decking boards, allowing you to secure boards down without visible fixings on the surface. Ideal for achieving a tidy, professional-looking installation across patios, gardens and outdoor living spaces.
