The Simpson Titen HD 5/8 in. x 6-1/2 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor sets the standard for concrete and masonry anchoring in demanding, corrosive environments. Built from Type 316 stainless steel and engineered with an innovative heat-treated carbon-steel cutting thread, this heavy-duty screw anchor delivers fast, reliable installation alongside long-lasting corrosion resistance - making it the ultimate solution for saltwater exposure, chemical environments, and any application where standard anchors fall short.

Key Features

• Qualified for static and seismic loading conditions - gives engineers and contractors confidence that the anchor meets code requirements for a broad range of structural applications.
• Undercutting thread design - efficiently transfers load directly to the base material, maximizing holding strength in concrete and masonry without relying on expansion force.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, reducing tool costs and simplifying the job site setup.
• Hex-washer head design - eliminates the need for a separate washer, saving time and delivering a clean, professional appearance after installation.
• Innovative carbon-steel cutting thread with limited carbon-steel content - effectively cuts into concrete while minimizing expansion stress on the base material, preserving edge distance integrity.
• Made from Type 316 stainless steel - provides superior corrosion resistance in saltwater, chemical, and other extreme environments where lesser materials would degrade over time.
• Single-use anchor design - installing the anchor only once prevents excessive thread wear and ensures full rated load capacity is maintained throughout the life of the connection.
• Installs with an impact wrench or hand tool using a 15/16 in. wrench - offers installation flexibility on any job site, whether power tools are available or not.

Why This Product

• Built for the harshest environments - Type 316 stainless steel is the optimal choice when saltwater, chemical exposure, or persistently wet and corrosive conditions are present, providing peace of mind that the anchor will perform for the long haul.
• Seismic and static qualification in one anchor - rather than sourcing different fasteners for different loading scenarios, this single screw anchor satisfies requirements for both static and seismic applications, streamlining product selection and procurement.
• Straightforward installation with no specialty tooling - compatibility with standard ANSI tolerance drill bits and common hand or impact tools means faster installation and fewer items to track on the job site.
• A trusted Simpson engineered solution - the Titen HD line combines proven undercutting thread technology with premium stainless steel construction, delivering a concrete and masonry anchoring system that balances installation efficiency with structural reliability.

Frequently Asked Questions

What makes Type 316 stainless steel the right choice for this anchor?

Type 316 stainless steel is the optimal choice for applications in corrosive or extreme environments such as saltwater, or when chemical or corrosive solutions are present. It provides superior long-lasting corrosion resistance compared to other stainless steel grades.

Do I need a special drill bit to install the Titen HD 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 the Titen HD screw anchor be removed and reinstalled?

No. Use a Titen HD screw anchor one time only - installing the anchor multiple times may result in excessive thread wear and reduce load capacity.

Is the Titen HD screw anchor approved for seismic applications?

Yes. The Titen HD screw anchor is qualified for both static and seismic loading conditions, making it suitable for use in seismically active areas and other demanding structural applications.
