The Simpson Titen HD 3/4 in. x 5 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor is engineered for concrete and masonry anchoring applications where corrosion resistance and installation efficiency cannot be compromised. Built from Type 304 stainless steel and featuring an innovative heat-treated carbon-steel cutting thread, this heavy-duty screw anchor delivers fast, reliable performance in wet, moist, or damp environments - making it a practical and cost-effective solution for projects that demand long-lasting holding power under both static and seismic loading conditions.

Key Features

• Qualified for static and seismic loading conditions - gives you confidence the anchor meets the structural demands of a wide range of code-required applications.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes holding strength in concrete and masonry by directing load directly into the substrate.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - reduces tool costs and keeps your crew moving without hunting down specialty equipment.
• Hex-washer head requires no separate washer - simplifies installation and delivers a clean, professional finished appearance.
• Innovative carbon-steel thread cuts concrete while limiting the amount of carbon steel in the anchor - less carbon steel means less expansion stress on the base material, reducing the risk of cracking near edges or in tight spacing situations.
• Made from Type 304 stainless steel - provides reliable corrosion resistance for installations in wet, moist, or damp environments without the cost premium of higher-grade alloys.
• Single-use design - the anchor is intended for one installation only, ensuring thread integrity and full load capacity are preserved at every use.
• Installs with an impact wrench or by hand tool using a 1 1/8 in. wrench - compatible with standard jobsite tools for flexible, efficient installation.

Why This Product

• Corrosion resistance built into the anchor body - Type 304 stainless steel construction makes this screw anchor a dependable long-term fastener in environments where moisture, humidity, or dampness would degrade a standard carbon-steel anchor over time.
• Cutting threads that work smarter in concrete and masonry - the heat-treated carbon-steel cutting threads undercut the base material as the anchor installs, creating a mechanical interlock that efficiently transfers load without requiring expansion force that could stress surrounding material.
• No additional hardware or specialty tools needed - the integrated hex-washer head eliminates the need for a separate washer, and standard ANSI tolerance drill bits handle the hole prep, keeping your installation process straightforward and your material list short.
• Engineered and backed by Simpson - this anchor carries seismic and static load qualifications, giving engineers, contractors, and inspectors a well-documented fastener solution they can specify and verify with confidence.

Frequently Asked Questions

Can the Titen HD screw anchor be removed and reinstalled in a different location?

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.

Does this anchor require a special drill bit for installation?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits, making it convenient for most job sites.

What type of stainless steel is used, and what environments is it suited for?

This anchor is made from Type 304 stainless steel, which 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 chemical exposure, Type 316 stainless steel is the recommended choice.

What tool is needed to drive the Titen HD screw anchor?

The Titen HD installs with an impact wrench or by hand tool using a 1-1/8 in. wrench size. The hex-washer head eliminates the need for a separate washer and provides a clean installed appearance.
