Titen HD® screw anchors are a trusted anchor solution because they offer the performance that specifiers need and the ease of installation that contractors demand. Until now, however, they were not for use in exterior or corrosive environments because they are heat-treated carbon steel. The stainless-steel Titen HD screw anchor (THDSS) for concrete and masonry sets the new standard for when the job calls for installation in any type of environment. The THDSS is the ultimate choice to provide fast and efficient installation, combined with long-lasting corrosion resistance that gives you an unsurpassed peace-of-mind on the jobsite.
Other stainless-steel bi-metal anchors are made by welding a full carbon segment onto the end of the anchor to facilitate cutting. Once installed, the carbon-steel segment embedded in the concrete is vulnerable to rust. As carbon steel rusts, it can expand up to ten times its original volume, cracking and damaging concrete if installed near an edge. The carbon-steel content of the stainless-steel Titen HD has been minimized to cut grooves in the concrete during installation, its mass is too small to cause concrete damage if it were to corrode.
The serrated threads on the tip of the stainless-steel Titen HD are vital because they undercut the concrete as the anchor is driven into the hole, making way for the rest of the threads to interlock with the concrete. In order for these threads to be durable enough to cut into the concrete, they are formed from carbon steel that is hardened.
For dry, interior applications, corrosion associated with carbon-steel is not a risk, but in many kinds of exterior, coastal or chemical environments, the anchor would be vulnerable to corrosion. With the introduction of the stainless-steel Titen HD, there is finally a state-of-the-art screw anchor solution that combines the corrosion resistance of Type 316 stainless steel with the undercutting ability of a heat-treated carbon-steel cutting threads.
