The Simpson Titen HD 1/2 in. x 3 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for demanding structural anchoring into both cracked and uncracked concrete and masonry. Its self-undercutting, non-expansion thread profile delivers outstanding performance under static and seismic loading conditions, making it a reliable solution for structural applications even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications, this zinc-plated anchor combines installation ease with the load performance required for serious structural work.

Key Features

• Qualified for static and seismic loading in cracked and uncracked concrete - gives builders and contractors confidence the anchor meets structural requirements across a wide range of real-world conditions.
• Self-undercutting thread design - efficiently transfers load directly to the base material, maximizing holding strength without relying on expansion pressure against the substrate.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, so there is no need to source specialty tooling or slow down the job.
• Hex-washer head design - eliminates the need for a separate washer, simplifying installation and delivering a clean, finished appearance once set.
• Specialized heat-treating process on carbon steel - creates tip hardness for cleaner cutting on installation without sacrificing the ductility needed for structural performance.
• Zinc-plated finish - provides corrosion resistance suitable for temporary exterior use, extending the anchor's versatility beyond interior-only applications.
• Single-use design - each anchor is intended for one-time installation only, ensuring thread integrity and full rated load capacity are maintained in the application.

Why This Product

• Engineered for both seismic and static demands - the Titen HD has been tested and shown to perform in cracked concrete under seismic loading, a critical qualification for structural anchoring in regions with strict code requirements.
• Installs with common jobsite tools - compatibility with standard ANSI tolerance drill bits and a 3/4 in. hex drive means faster, simpler installations without specialized equipment or additional hardware.
• Versatile across concrete and masonry applications - the non-expansion, self-undercutting design supports use at reduced edge distances and spacings, opening up anchoring options that traditional expansion anchors cannot reliably handle.
• A trusted heavy-duty anchor from Simpson - backed by Simpson's engineering and rigorous testing for structural applications, this screw anchor is built to meet the performance standards that structural and seismic installations demand.

Frequently Asked Questions

Can the Titen HD anchor be used in cracked concrete?

Yes. The Titen HD is specifically designed for optimum performance in both cracked and uncracked concrete. It has been tested and shown to provide outstanding performance under both static and seismic loading conditions in cracked concrete.

Do I need a special drill bit to install the Titen HD anchor?

No special drill bit is required. The Titen HD anchor is designed to install using standard-sized ANSI tolerance drill bits, making installation straightforward with common jobsite equipment.

Can the Titen HD anchor be reused or reinstalled?

No. The Titen HD screw anchor is intended for one-time use only. Installing the anchor multiple times may result in excessive thread wear and reduce load capacity, compromising the integrity of the connection.

Is the Titen HD anchor suitable for outdoor use?

The zinc-plated carbon steel Titen HD anchor is recommended for permanent dry interior non-corrosive environments. It is suitable for temporary outdoor applications but is not intended for permanent exterior or corrosive environments.
