TimberTech CONCEALoc Hidden Fastener

CONCEALoc Hidden Fasteners deliver a clean, screw-free composite deck surface, attaching boards at the joist through their grooved edges for a smooth, barefoot-friendly finish. Consistent spacing supports proper expansion, contraction, and drainage across the deck. Heavy-gauge, corrosion-resistant steel construction holds up to long-term outdoor exposure, and each fastener locks boards firmly in place while allowing for natural seasonal movement. CONCEALoc is designed exclusively for TimberTech and AZEK grooved composite decking — it's not a universal fit for other brands' boards.
