Buying Guide
- Board type compatibility: Confirm whether fasteners are designed for solid wood, composite, WPC, or a mix of materials. Some clips are tailored to grooved boards, others to solid-edge boards.
- Expansion gap requirements: Most hidden fasteners require a specific gap (commonly around 6mm) to prevent warping and ensure uniform spacing.
- Material and corrosion resistance: Stainless steel (especially 316 marine-grade) offers superior rust resistance for outdoor use; polymer-based fasteners may provide easy installation and weather resistance but vary by product.
- Included hardware: Some sets include screws; others require separate purchase. Check whether screws match your board thickness and material.
- Project scale: Larger packs (e.g., 200+ pieces) are cost-effective for big decks or future expansions, while smaller packs suit repairs or sample testing.
- Installation considerations: Some systems require pre-drilling or specific drill bits; verify compatibility with your tools and deck design.
- Aesthetic outcome: Hidden fasteners are chosen to minimise visible hardware. Consider the finish (black, stainless, or polymer) to match your decking style.
- Warranty and durability: Look for products with UV resistance and long-term durability claims, especially for outdoor use in the UK climate.
