The Simpson Titen HD 1/4 in. x 3 in. Heavy-Duty Screw Anchor is a high-strength concrete and masonry screw anchor engineered for optimum performance in both cracked and uncracked concrete under static and seismic loading conditions. Its self-undercutting, non-expansion design makes it a trusted choice for structural applications where reduced edge distances and spacings are required, while the zinc-plated carbon steel construction suits permanent dry interior environments and temporary outdoor use.

Key Features

• Qualified for static and seismic loading in cracked and uncracked concrete - gives structural engineers and contractors confidence that the anchor meets demanding code requirements without special concessions.
• Self-undercutting thread design - efficiently transfers load directly into the base material, maximizing holding strength and reducing the risk of pullout in critical connections.
• No special drill bit required - installs with standard-sized ANSI tolerance drill bits, keeping the tool setup simple and cutting down on job-site prep time.
• Hex-washer head with integrated bearing surface - eliminates the need for a separate washer, speeding up installation and delivering a clean, professional finished appearance.
• Specialized heat-treating process on carbon steel - creates tip hardness for cleaner cutting action while preserving ductility, so the anchor performs reliably without becoming brittle under load.
• Zinc-plated finish - provides a level of corrosion resistance suitable for temporary exterior applications, extending the anchor's versatility beyond strictly indoor use.
• Single-use design - the Titen HD screw anchor is intended for one-time installation only; reinstalling the anchor can cause excessive thread wear and reduce load capacity, so plan placement carefully before driving.

Why This Product

• Engineered for the most demanding structural conditions - tested and proven in both cracked concrete and seismic loading scenarios, this heavy-duty screw anchor is appropriate for structural connections where failure is not an option.
• Installs faster with tools you already own - because standard ANSI tolerance drill bits are all that is needed and the hex-washer head requires no separate washer, crews can complete concrete anchor installations quickly without sourcing specialty hardware.
• Performs where tight spacing matters - the non-expansion, self-undercutting design allows use at reduced edge distances and spacings, giving installers more flexibility in confined layouts that would challenge traditional expansion anchors.
• Balanced hardness and toughness in one anchor - Simpson's heat-treating process delivers a tip that cuts cleanly into concrete while keeping the body ductile, producing consistent, reliable results across a wide range of masonry and concrete applications.

Frequently Asked Questions

Can the Titen HD anchor be used in cracked concrete?

Yes. The Titen HD is specifically designed and tested for optimum performance in both cracked and uncracked concrete under both static and seismic loading conditions.

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, making installation straightforward with common tools.

Can the Titen HD anchor be removed and 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 its 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.
