The Simpson Titen HD 1/2 in. x 6-1/2 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor is a premium concrete and masonry anchoring solution engineered for corrosive, extreme, and demanding environments where long-term reliability is non-negotiable. Built from Type 316 stainless steel and paired with an innovative heat-treated carbon-steel cutting thread, this screw anchor delivers fast, efficient installation without sacrificing the corrosion resistance required for saltwater exposure, chemical contact, or other highly aggressive conditions. Whether securing structural connections in coastal construction or industrial settings, this anchor combines proven load performance with lasting peace of mind.

Key Features

• Qualified for static and seismic loading conditions - meets the structural demands of both standard and seismic applications, giving engineers and installers confidence in code-sensitive projects.
• Thread design undercuts to efficiently transfer the load to the base material - optimized load transfer means a more secure connection in concrete and masonry without relying on expansion force alone.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - reduces tool costs and jobsite complexity by working with the equipment crews already have on hand.
• Hex-washer head requires no separate washer - the integrated head provides a clean installed appearance and eliminates an extra component from the installation process.
• Innovative carbon-steel thread that effectively cuts the concrete while significantly limiting the amount of carbon steel in the anchor - less carbon steel in the body means less expansion stress on the base material, reducing the risk of cracking near edges or in tight layouts.
• Made from Type 316 stainless steel for superior corrosion resistance - the optimal material choice when saltwater, chemicals, or corrosive solutions are present, providing lasting performance where standard steel anchors would fail prematurely.
• Installs with an impact wrench or by hand tool - installation flexibility lets crews work efficiently regardless of the tools available on site.
• Single-use design - installing the anchor one time only preserves thread integrity and maintains rated load capacity; reinstallation may cause excessive thread wear and reduce performance.

Why This Product

• Built specifically for extreme environments - Type 316 stainless steel is the optimal choice when saltwater, chemical exposure, or persistently corrosive conditions are present, making this anchor a purpose-matched solution rather than a generic upgrade.
• Seismic and static qualification in one anchor - the Titen HD is qualified for both static and seismic loading conditions, reducing the need to source different anchors for different code requirements on the same project.
• Faster installation with no extra hardware - the hex-washer head eliminates separate washers, and the standard ANSI tolerance drill bit compatibility means no special tooling is needed, cutting both material cost and installation time.
• Engineered load transfer with minimal base-material stress - the undercutting thread design transfers load efficiently to the base material while the limited carbon-steel thread construction reduces expansion forces, supporting reliable performance in concrete and masonry alike.

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 salt water, or when chemical or corrosive solutions are present. It offers superior corrosion resistance compared to other grades, making it ideal for demanding outdoor or industrial settings where long-lasting performance is critical.

Do I need a special drill bit to install the Titen HD screw anchor?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits with a 1/2 in. diameter, 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, potentially compromising the integrity of the connection.

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 a reliable choice for structural applications in seismic zones where code-compliant performance is required.
