The Simpson Titen HD 3/4 in. x 6 in. Heavy-Duty Screw Anchor is a high-strength concrete and masonry screw anchor engineered for optimum performance in both cracked and uncracked concrete. Its self-undercutting, non-expansion design makes it a reliable choice for demanding structural applications, including those subject to seismic loading, while a specialized heat-treating process and standard ANSI tolerance drill bit compatibility keep installation straightforward on the job site.

Key Features

• Qualified for static and seismic loading conditions - gives engineers and contractors confidence when anchoring into concrete in seismic zones or under dynamic loads.
• Self-undercutting thread design - efficiently transfers load directly into the base material, delivering strong, reliable holding power without the need for expansion force that can stress concrete near edges.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, saving time and eliminating the need for proprietary tooling on the job site.
• Hex-washer head design - eliminates the need for a separate washer, speeding up installation and leaving a clean, professional finished appearance.
• Specialized heat-treating process on carbon steel - creates tip hardness for cleaner cutting while preserving ductility, so the anchor cuts efficiently without becoming brittle under structural loads.
• Zinc-plated finish - makes the anchor suitable for temporary outdoor or exterior applications in addition to permanent dry interior environments, adding flexibility across job site conditions.
• Single-use design - the anchor is intended for one-time installation only, as reinstalling may cause excessive thread wear and reduce load capacity, ensuring the connection performs as engineered.

Why This Product

• Proven in the most demanding concrete anchoring scenarios - the Titen HD has been tested and shown to provide outstanding performance in cracked concrete under both static and seismic loading, making it one of the few heavy-duty screw anchors suitable for structural seismic applications.
• Ideal for tight, high-load installations - the non-expansion, self-undercutting mechanics allow structural use even at reduced edge distances and spacings, giving more flexibility in layout without sacrificing holding strength.
• Fast, tool-friendly installation - compatibility with standard ANSI tolerance drill bits and a hex-washer head that needs no separate washer means fewer parts to manage and a faster overall installation process.
• Versatile across concrete and masonry applications - from permanent interior structural connections to temporary exterior anchoring, this carbon steel screw anchor covers a wide range of approved applications, reducing the need to stock multiple anchor types.

Frequently Asked Questions

Can the Titen HD screw anchor be used in cracked concrete?

Yes. The Titen HD is specifically designed for optimum performance in both cracked and uncracked concrete, and 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 is designed to install using standard-sized ANSI tolerance drill bits, simplifying the installation process.

Can the Titen HD anchor be removed and reinstalled?

No. The Titen HD screw anchor should be used one time only. Installing the anchor multiple times may result in excessive thread wear and reduce load capacity.

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 or temporary outdoor applications. It is not intended for permanent exterior or corrosive environment use.
