The Titen HD screw anchor from Simpson Strong-Tie provides a high-strength connection for concrete and masonry. The patented anchor is now code listed for use in both cracked and uncracked concrete, meeting the requirements of the new 2006 International Building Code (IBC) for post-installed anchors. As an anchoring solution for all types of fixtures and base plates, the Titen HD anchor is available in 3/8"-3/4" diameters. The threaded design requires less installation torque, allowing for quick and easy installation. The anchor installs with standard size drill bits and is removable.
