About This Product

The Titen HD anchor is a high-strength screw anchor for concrete and masonry. It is designed for optimum performance in both cracked and uncracked concrete. The high-strength, easy-to-install Titen HD anchor has been tested and shown to provide outstanding performance in cracked and uncracked concrete under both static and seismic loading conditions. The self-undercutting, non-expansion characteristics of the Titen HD anchor make it ideal for structural applications, even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.

Highlights

  • Qualified for static and seismic loading conditions
  • Thread design undercuts to efficiently transfer the load to the base material
  • No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits
  • Testing shows the Titen HD installs in concrete with 50% less torque than competitor anchors
  • Hex-washer head requires no separate washer and provides a clean installed appearance
  • Carbon steel Titen HD utilizes a specialized heat-treating process that creates tip hardness for better cutting without compromising the ductility
  • Zinc-plated carbon steel anchor can be used for temporary exterior applications
  • Size: 5/8 in. x 8 in.
  • Caution: Use a Titen HD screw anchor one time only - installing the anchor multiple times may result in excessive thread wear and reduce load capacity
  • Code compliance verified by ICC-ES Evaluation Report(s): ESR-2713 (Concrete), ESR-1056 (Masonry), ESR-2713 (Concrete) - Spanish, ESR-5915; State of Florida product approval(s): FL15730

Questions & Answers

If I'm using a 1/2" anchor screw and the thickness of my slab is 7 inches thick, can I use a 6.50" long screw or would a 6" screw be better? I'd like the anchoring power of the 6.50" but will not use it if there is high risk of a blowout at the bottom.

          How many threads does the 8” Titen HD anchor bolt have? One picture shows significantly fewer (with a large portion of the bolt without threads) while the other picture shows threads all the way to the bolt head.

          Answer This Question

          Hi Matt, this is Bekah from Simpson Strong-Tie. The THD series has different thread lengths and some do go all the way to the head while longer THD's the thread doesn't go all the way to the head. The THDB62800HF1 has a thread length of 5 1/2" so it will not go all the way to the head. If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you.​​

                  They are a bit bigger than a standard 3/8 bolt due to the raised threads and would not fit thru the predrilled 3/8 holes in my sliding gate track. I didn't want to have to drill out 40 holes in the track and mess up the galvanizing, so I returned them and bought 1/4" Strong-Tie Titen HD screw anchors instead. The end result looks nice and works perfect.

                  They are strong and they fit the ties perfectly. I drilled per instructions, put epoxy in the holes, and they drove in perfectly with a cordless impact driver.
