The information on this page is intended for preliminary guidance only. For complete safety and to verify accurate information, please consult the (PDF linked below) to obtain the manufacturer’s values when selecting the anchors for your project.

Simpson Strong-Tie® mechanical anchors are designed to install easily and securely into a variety of base materials, including concrete, grouted and hollow CMU and brick. Specifiers and contractors trust Simpson Strong-Tie anchors for optimum performance under the most demanding structural applications. The stainless-steel Titen screws attach various types of components to concrete and masonry in environments where a medium level of corrosion resistance is required. Available in hex and Phillips head, Titen screws are designed for use with appropriately sized drill bits that are included with each box.


  1. Drill a hole in the base material using the appropriate diameter carbide drill bit as specified in the table. Drill the hole to the specified embedment depth plus 1/2" to allow the thread tapping dust to settle and blow it clean using compressed air. Overhead installations need not be blown clean. Alternatively, drill the hole deep enough to accommodate embedment depth and dust from drilling and tapping.
  2. Position fixture, insert screw and tighten using drill and Titen screw installation tool fitted with a hex socket or Phillips bit.

Preservative-treated wood applications: suitable for use in non-ammonia formulations of CCA, ACQ-C, ACQ-D, CA-B, SBX/DOT and zinc borate. Acceptable for use in exterior environments. Use caution not to damage coating during installation. The 410 stainless-steel Titen with top coat provides “medium” corrosion protection. Recommendations are based on testing and experience at time of publication and may change. Simpson Strong-Tie cannot provide estimates on service life of screws.


  • Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. Steps must be taken to prevent inadvertent sustained loads above the listed allowable loads. Overtightening and bending moments can initiate cracks detrimental to the hardened screw’s performance. Use the Simpson Strong-Tie Titen installation tool kit as it has a bit that is designed to reduce the potential for overtightening the screw.
  • Oversized holes in the base material will reduce or eliminate the mechanical interlock of the threads with the base material and will reduce the anchor’s load capacity.
  • Installation of concrete screw generally is influenced by many factors such as but not limited to, concrete compressive strength, type of aggregate, installation location, installation direction and tools used for installation.
