EXTREME Ipe Clip BROWN hidden deck fasteners with a 3/32 in. gap are simple to install. They allow DIY homeowners and builders a high-end, fastener-free, and smooth decking surface. The EXTREME fastener features an edge-mount method for connecting hardwood deck boards, making these fasteners nearly invisible. This patented design provides camouflage between the board gaps, hiding the deck clip out of sight. The EXTREME is constructed of a polyethylene resin that adds both chemical and UV resilient properties. EXTREME hidden fasteners are made with a tough black oxide coated stainless steel insert that solidly holds decking to joists for a long lasting hold-down. These fasteners have been put to the test to be up to 3X stronger than other invisible deck clips and deck fastening systems. Deck boards are secured only on one side. This allows for the natural expansion and contraction of hardwood decking on its width. As a biscuit-style deck fastener, it fits into the edge groove of the board. Installers can easily router the 5/32 in. edge groove on site, use a biscuit joiner to cut slots, or invest in pre-grooved hardwood deck boards. Deck screws are pre-drilled and set at a 45° angle through the EXTREME clip into the lower groove edge of the board. The deck screw then continues down into the joist below. Installing each hardwood deck board utilizing the EXTREME fastener clip will repeatedly produce consistent gap spacing due to the incorporated gap spacer leg on the clip.
