Designed exclusively for TimberTech grooved boards, these hidden fasteners deliver a sleek, professional look while ensuring long-lasting durability. Made from SAE 304 stainless steel, the clips provide superior corrosion resistance d to regular steel, making them i for outdoor use season after season. Installation is versatile and can be done pneumatically with the FastenMaster TigerClaw Gun or manually with a drill. The brown-colored clips blend seamlessly with the framing in the gaps between deck boards, although they are not color-matched to the decking itself. These fasteners can be used on angles up to 45 degrees, with specific guidance for offsetting the screw to avoid joist side exit. They maintain consistent spacing between boards and can be paired with deck spacers if desired. Please note that CONCEALoc® fasteners are not compatible with steel or aluminum framing due to the angled screw installation method. This package includes 175 stainless steel clips and 184 stainless steel screws, providing everything needed for a 100 square foot deck installation. Model Number: CLOCFAST
