The THDSS screw anchor’s cutting ability comes from a proprietary bi-metal design that uses a carbon-steel helical-coil thread brazed into the shank of the anchor. These serrated carbon-steel threads undercut the concrete allowing subsequent threads to interlock with the concrete.

Other stainless-steel bi-metal anchors are made by welding a full carbon segment onto the end of the anchor to facilitate cutting. In the stainless-steel Titen HD, the carbon steel is confined to the helical-coil thread to limit concrete damage when it corrodes.

Key features and benefits of the THDSS screw anchor:
Ideal for exterior applications and corrosive environments
Type 316 stainless steel
Minimized carbon steel for less corrosion expansion
Installs with an impact wrench or a hand tool
