Deck builders working near the coast will be interested in Simpson Strong-Tie’s new Titen HD heavy-duty screw anchors for concrete and masonry. Made with Type 316 stainless steel, the screws’ proprietary bi-metal design features a carbon-steel helical-coil thread brazed into the stainless steel shank of the anchor, rather than a full carbon steel segment welded onto the end of the anchor. According to the manufacturer, a 1/2-inch-by-5-inch THDSS screw anchor contains less than 1% carbon steel while other stainless steel screw anchors of the same size can contain up to 18% carbon steel, which can expand and crack the surrounding concrete as it corrodes. Titen HD screw anchors can be installed with an impact wrench or a hand tool. strongtie.com
