Simpson Titen HD 1/2 in. x 5 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor delivers fast, reliable fastening in concrete and masonry applications where moisture, humidity, or damp conditions demand long-lasting corrosion resistance. Built from Type 304 stainless steel with an innovative heat-treated carbon-steel cutting thread, this heavy-duty screw anchor combines the durability of stainless construction with the undercutting performance needed for efficient load transfer - making it a practical, cost-effective solution for general construction projects in wet or moist environments.

Key Features

• Qualified for static and seismic loading conditions - gives buyers confidence that the anchor meets demanding structural performance requirements for a wide range of applications.
• Thread design undercuts to efficiently transfer the load to the base material - means a more secure, reliable hold in concrete and masonry without relying on expansion forces alone.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - saves time and reduces costs by working with common jobsite equipment already on hand.
• Hex-washer head requires no separate washer - simplifies installation and delivers a clean, finished appearance without additional hardware.
• Innovative carbon-steel cutting thread limits the amount of carbon steel in the anchor - less carbon steel means less expansion, reducing stress on the base material while still cutting through concrete effectively.
• Installs with an impact wrench or by hand tool - offers installation flexibility so crews can work efficiently with whichever tool is most practical on site.
• Single-use design - using the anchor one time only preserves full thread integrity and maintains rated load capacity, ensuring the connection performs as specified.

Why This Product

• Corrosion resistance where it counts - Type 304 stainless steel construction makes this anchor a cost-effective, long-lasting choice for concrete and masonry fastening in wet, moist, or damp conditions, without the higher cost of Type 316 when extreme or saltwater exposure is not a factor.
• Seismic and static load qualification - the Titen HD is engineered and qualified for both static and seismic loading conditions, making it suitable for projects where code-compliant, structurally verified anchoring is required.
• No specialty tooling needed - compatibility with standard ANSI tolerance drill bits and installation by impact wrench or hand tool means no additional equipment investment, keeping the installation process straightforward and efficient.
• Designed for dependable one-time installation - the single-use engineering approach ensures that when the anchor is set correctly the first time, thread integrity and full load capacity are preserved for the life of the connection.

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 screw anchor is designed to install using standard-sized ANSI tolerance drill bits, making it convenient for use with common jobsite equipment.

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.

What is the difference between Type 304 and Type 316 stainless steel for this anchor?

Type 304 stainless steel 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 this anchor rated for seismic applications?

Yes. The Simpson Titen HD screw anchor is qualified for both static and seismic loading conditions, making it suitable for use in seismically active regions where anchoring performance under dynamic loads is required.
