The Simpson Titen HD 1/2 in. x 6-1/2 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor is a professional-grade concrete and masonry anchor engineered for reliable performance in wet, moist, or damp conditions. Simpson combines the corrosion resistance of Type 304 stainless steel with an innovative heat-treated carbon-steel cutting thread, delivering fast, efficient installation and dependable load capacity for both static and seismic applications. Whether anchoring into concrete or masonry, this heavy-duty screw anchor offers a streamlined installation process and a clean finished result - making it a trusted choice for demanding construction and structural projects.

Key Features

• Qualified for static and seismic loading conditions - gives you confidence the anchor meets code requirements for a wider range of structural applications, including seismic zones.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes holding strength in concrete and masonry so the anchor performs reliably under real-world loads.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - saves time and money by working with tools already on the job site.
• Hex-washer head requires no separate washer - simplifies installation and delivers a clean, professional appearance without extra hardware.
• Innovative carbon-steel cutting thread limits the amount of carbon steel in the anchor - less carbon steel means less expansion in the base material, reducing the risk of cracking or damage during installation.
• Made from Type 304 stainless steel - provides long-lasting corrosion resistance in wet, moist, or damp environments, extending the service life of the anchor without the cost of higher-grade alloys.
• Installs with an impact wrench or by hand tool using a 3/4 in. wrench - flexible installation options let crews work efficiently with the equipment they have on hand.
• Single-use design - the anchor is engineered to be installed one time only; re-installation may result in excessive thread wear and reduced load capacity, so proper planning before driving the anchor protects structural integrity.

Why This Product

• Corrosion resistance without over-engineering the spec - Type 304 stainless steel delivers meaningful protection against rust and degradation in wet or damp environments, making it a cost-effective upgrade over carbon-steel anchors where moderate corrosion resistance is the priority.
• Seismic and static qualification in one anchor - because the Titen HD is qualified for both static and seismic loading conditions, contractors can specify a single anchor solution across a broader range of project requirements rather than sourcing multiple products.
• Faster installation with no specialty tooling - compatibility with standard ANSI tolerance drill bits and a 3/4 in. hex drive means crews can complete concrete and masonry anchoring work quickly without sourcing proprietary bits or adapters.
• Built-in load transfer through undercutting thread technology - the thread design actively undercuts the base material as it drives, creating a mechanical interlock that efficiently transfers load and supports strong, consistent holding values in concrete and masonry substrates.

Frequently Asked Questions

What type of environments is the Type 304 stainless steel version best suited for?

Type 304 stainless steel is a cost-effective solution for less extreme applications where the environment may be wet, moist, or damp. For highly corrosive or extreme environments such as salt water or where chemical or corrosive solutions are present, Type 316 stainless steel is the recommended choice.

Do I need a special drill bit to install this screw anchor?

No special drill bit is required. The Titen HD screw anchor is designed to install using standard-sized ANSI tolerance drill bits, simplifying the installation process.

Can this anchor be removed and reinstalled in the same hole?

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 its load capacity.

Is this anchor rated for seismic applications?

Yes. The Simpson Titen HD screw anchor is qualified for both static and seismic loading conditions, making it suitable for use in regions with seismic requirements.
