The Simpson Titen HD 3/8 in. x 6 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor sets the standard for reliable anchoring in concrete and masonry, delivering fast and efficient installation combined with long-lasting corrosion resistance. Built from Type 304 stainless steel and engineered with an innovative carbon-steel thread that undercuts the base material as it drives, this heavy-duty screw anchor is the go-to solution for structural anchoring in wet, moist, or damp environments where performance and durability cannot be compromised.

Key Features

• Qualified for static and seismic loading conditions - gives installers and engineers confidence that this anchor meets the structural demands of seismic zones as well as standard load applications.
• Undercutting thread design - efficiently transfers the load directly to the base material, maximizing holding strength in concrete and masonry without relying on expansion force alone.
• No special drill bit required - works with standard-sized ANSI tolerance drill bits, so installers can get the job done faster without sourcing specialized tooling.
• Hex-washer head design - eliminates the need for a separate washer, reducing hardware count and delivering a clean, professional installed appearance.
• Innovative carbon-steel cutting thread on a stainless body - the carbon-steel thread cuts efficiently into concrete while minimizing the total amount of carbon steel in the anchor, meaning less expansion stress on the base material and a cleaner installation.
• Type 304 stainless steel construction - provides reliable corrosion resistance in wet, moist, or damp environments, making this a cost-effective choice where extreme corrosive exposure is not a primary concern.
• Installs with an impact wrench or hand tool using a 9/16 in. wrench - offers installation flexibility whether working on a large project with power tools or in tight spaces requiring manual control.
• Single-use anchor design - engineered for one-time installation to ensure maximum thread integrity and full rated load capacity; reinstallation may reduce performance.

Why This Product

• Corrosion resistance without sacrificing cutting performance - the Titen HD uniquely combines Type 304 stainless steel with heat-treated carbon-steel cutting threads, so buyers get the long-term durability of stainless and the proven cutting action needed for clean, secure seating in concrete and masonry.
• Seismic and static dual qualification - unlike basic screw anchors, this anchor is qualified for both static and seismic loading conditions, making it a reliable choice for projects in seismic zones where code compliance is required.
• Simplified installation with no specialty tooling - compatibility with standard ANSI tolerance drill bits and common hand or impact wrenches means faster setup, less equipment overhead, and a straightforward process for professional contractors and serious DIYers alike.
• Purpose-built for demanding wet and damp environments - where a standard carbon-steel anchor would corrode and fail over time, the Type 304 stainless steel construction ensures lasting integrity in exterior, below-grade, or moisture-prone anchoring applications.

Frequently Asked Questions

What base materials is the Titen HD THD37600H4SS designed for?

The Titen HD screw anchor is designed for installation in concrete and masonry, making it suitable for a wide range of structural anchoring applications in these base materials.

Can the Titen HD anchor be reused or reinstalled multiple times?

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.

Do I need a special drill bit to install the THD37600H4SS?

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

Is this anchor rated for seismic applications?

Yes. The Titen HD THD37600H4SS is qualified for both static and seismic loading conditions, making it appropriate for use in seismic zones where such ratings are required.
