(20 Pack) Simpson Strong-Tie THD50800H6SS 1/2-Inch x 8-Inch 316 Stainless Steel Heavy-Duty Screw Anchors - Ideal for Concrete, Masonry & Structural Fastening in Outdoor & Marine Applications

The Titen HD screw anchor is for use in cracked and uncracked concrete and masonry. It is the ultimate choice to provide fast and efficient installation. The Titen HD (THD) is designed for dry, interior, non-corrosive environments. The Titen HD stainless steel (THDSS) is for use in severe environments where exposure to the elements and corrosion is a concern. Key Features THD and THDSS — Qualified for static and seismic loading conditions THD and THDSS — Thread design undercuts to efficiently transfer the load to the base material THD and THDSS — Standard fractional sizes THD and THDSS — No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits THD and THDSS — Testing shows the Titen HD installs in concrete with 50% less torque than competitor anchors THD and THDSS — Hex-washer head requires no separate washer and provides a clean installed appearance THDSS — Innovative carbon-steel thread effectively cuts the concrete while significantly limiting the amount of carbon-steel in the anchor; less carbon steel, less expansion Material THDSS — Type 316 stainless steel with carbon-steel lead-threads 1/2" diameter Titen HD anchors achieve sufficient embedment depth to develop tension loads equal to many Simpson Strong-Tie holdowns that specify a 5/8" diameter anchor. Testing has been conducted to assure compatibility of these holdowns’ anchor holes with the 1/2" Titen HD screw anchor.
