The Simpson Titen HD 1/2 in. x 15 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for structural anchoring in both cracked and uncracked concrete and masonry. Its self-undercutting, non-expansion design allows it to perform reliably under static and seismic loading conditions, even at reduced edge distances and spacings - making it a dependable choice for demanding structural concrete and masonry applications. Zinc-plated for corrosion resistance, it is recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.

Key Features

• Qualified for static and seismic loading conditions in cracked and uncracked concrete - gives structural professionals confidence that this anchor meets performance requirements across a wide range of real-world loading scenarios.
• Self-undercutting thread design efficiently transfers load to the base material - delivers strong, reliable holding power in concrete and masonry without relying on expansion force, making it suitable for use at reduced edge distances and spacings.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, reducing tooling costs and simplifying the installation process on the job site.
• Hex-washer head requires no separate washer - speeds up installation and provides a clean, finished appearance once the anchor is set.
• Specialized heat-treating process creates tip hardness without sacrificing ductility - allows the anchor to cut cleanly into concrete and masonry while maintaining the structural toughness required for heavy-duty applications.
• Zinc-plated carbon steel construction - provides a level of corrosion resistance appropriate for temporary exterior use, extending the anchor's versatility beyond strictly indoor environments.
• Single-use design - the anchor should be installed one time only, as reinstalling may cause excessive thread wear and reduce load capacity, which is an important consideration when planning your installation.

Why This Product

• Dual-condition concrete performance - the Titen HD is specifically engineered and tested for optimum performance in both cracked and uncracked concrete under static and seismic conditions, making it one of the few heavy-duty screw anchors suited to seismic-zone structural work.
• Simplified installation with no specialty tooling - because standard ANSI tolerance drill bits are all that is needed, contractors and installers can complete the job faster and without investing in dedicated equipment.
• Structural versatility at tight spacings - the non-expansion, self-undercutting design allows use at reduced edge distances and spacings where traditional expansion anchors may not be permitted, opening up more placement options in structural concrete applications.
• Trusted Simpson engineering for long-term structural integrity - backed by Simpson's rigorous testing and heat-treating process, this carbon steel anchor is built to maintain ductility and load capacity in demanding permanent interior structural anchoring applications.

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 and uncracked concrete.

Does the Titen HD require a special drill bit for installation?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits, simplifying the installation process and reducing the need for specialized tooling.

Can the Titen HD screw 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, which could compromise structural integrity.

Is the Titen HD suitable for outdoor use?

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