The CONCEALoc Hidden Fastener for Composite Decking is designed to deliver a clean, professional-looking deck surface by securing boards without visible screws. This hidden fastening system attaches deck boards at the joist through the grooved edges, creating a smooth, barefoot-friendly finish while maintaining consistent spacing for proper expansion, contraction, and drainage.
Engineered for durability, CONCEALoc fasteners are made from high-strength, corrosion-resistant materials suitable for long-term outdoor exposure. Each fastener locks deck boards firmly in place, reducing board movement while allowing natural seasonal changes. The system is compatible with many popular composite decking brands that use a standard grooved profile, making it a versatile choice for both new installations and repairs.
Installation is fast and efficient when used with a compatible CONCEALoc or Trex installation tool, helping ensure uniform alignment and spacing across the deck surface. This results in a polished, professional appearance with no surface fasteners to distract from the look of the decking. Each pack is sized to cover approximately 50 linear feet of decking, making it ideal for smaller projects, touch-ups, or finishing sections of a deck.
