The Simpson Titen HD 1/2 in. x 3 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor is engineered for concrete and masonry anchoring applications where reliable corrosion resistance and fast, straightforward installation are essential. Built from Type 304 stainless steel with innovative heat-treated carbon-steel cutting threads, this heavy-duty screw anchor delivers lasting performance in wet, moist, or damp environments - making it a cost-effective stainless solution for projects that demand durability without the premium of Type 316. Qualified for both static and seismic loading conditions, it is a dependable choice for professionals who need a concrete screw anchor that installs efficiently and holds with confidence.

Key Features

• Qualified for static and seismic loading conditions - meets the structural requirements for a wide range of code-compliant applications, giving contractors confidence in safety-critical installations.
• Thread design undercuts to efficiently transfer the load to the base material - the undercutting action creates a mechanical interlock directly in the concrete or masonry, maximizing holding strength without anchoring aids.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - works with common jobsite equipment so there is no need to purchase proprietary tooling, saving time and expense.
• Hex-washer head requires no separate washer and provides a clean installed appearance - the integrated head design eliminates an extra component, speeds up installation, and leaves a finished, professional look.
• 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 anchor body means less expansion stress on the base material, reducing the risk of edge or spacing failures.
• Installs with an impact wrench or by hand tool using a 3/4 in. wrench - flexible installation options let crews use the tools already on hand, whether working in tight spaces or on open structure.
• Single-use design - using the anchor one time only preserves full thread integrity and rated load capacity, ensuring the installed connection performs exactly as engineered.

Why This Product

• Corrosion resistance built for real-world wet conditions - the Type 304 stainless steel construction is specifically suited for environments that are wet, moist, or damp, providing long-lasting protection without overpaying for a Type 316 anchor where extreme corrosive exposure is not a factor.
• Seismic and static load qualification in a single anchor - because this concrete screw anchor is qualified for both loading conditions, it simplifies product selection and purchasing for projects where seismic performance documentation is required alongside standard structural loads.
• Faster installations with no specialty tooling or additional hardware - the combination of standard ANSI tolerance drill bit compatibility, an integrated hex-washer head, and impact wrench or hand-tool installation means fewer steps, fewer parts, and faster job completion on masonry and concrete anchoring work.
• Proven Simpson engineering for heavy-duty anchoring - the Titen HD screw anchor line is a recognized benchmark in concrete and masonry anchoring, and this stainless version carries that same structural pedigree into corrosion-sensitive applications where a standard carbon-steel anchor would not hold up over time.

Frequently Asked Questions

What type of drill bit is required 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, making it straightforward to use with common jobsite equipment.

Can the Titen HD screw anchor be removed and reinstalled?

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

What is the difference between Type 304 and Type 316 stainless steel Titen HD anchors?

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

Is the Titen HD screw anchor approved for seismic applications?

Yes. The Titen HD is qualified for both static and seismic loading conditions, making it suitable for use in seismically active regions and projects with strict structural requirements.
