The Simpson Titen HD 1/2 in. x 8 in. Type 316 Stainless-Steel Heavy-Duty Screw Anchor sets the standard for concrete and masonry anchoring in corrosive and extreme environments. This state-of-the-art screw anchor combines the superior corrosion resistance of Type 316 stainless steel with an innovative heat-treated carbon-steel cutting thread design, delivering fast, efficient installation and long-lasting performance where it matters most - from saltwater-exposed structures to areas where chemical or corrosive solutions are present. Whether you are working on demanding marine applications or heavy-duty structural connections, this heavy-duty screw anchor is engineered to perform.

Key Features

• Qualified for static and seismic loading conditions - gives you confidence that the anchor meets code requirements for both everyday structural loads and earthquake-prone regions.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes holding strength in concrete and masonry, reducing the risk of pull-out under heavy loads.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - saves time and money by eliminating the need for specialized tooling on the job site.
• Hex-washer head requires no separate washer - simplifies installation and delivers a clean, professional finished appearance without extra hardware.
• Innovative carbon-steel thread effectively cuts the concrete while significantly limiting the amount of carbon steel in the anchor - less carbon steel means less expansion and a cleaner, more controlled installation with reduced stress on the base material.
• Made from Type 316 stainless steel - provides superior, long-lasting corrosion resistance for applications in saltwater, chemical, or other extreme environments where standard anchors would degrade.
• Installs with an impact wrench or by hand tool using a 3/4 in. wrench - offers installation flexibility so crews can work efficiently with the tools already on hand.
• Single-use design - the anchor is engineered for one-time installation; this ensures thread integrity is never compromised and that rated load capacity is fully maintained.

Why This Product

• Purpose-built for the harshest conditions - Type 316 stainless steel is the optimal choice when anchors will be exposed to saltwater, moisture, or corrosive chemical solutions, making this anchor a reliable long-term investment in environments where lesser materials fail prematurely.
• Seismic and static load qualification - for contractors and engineers working in areas subject to seismic activity, this anchor provides documented performance under both static and seismic loading conditions, supporting code-compliant installations.
• Streamlined installation with no specialty tooling - because the Titen HD works with standard ANSI tolerance drill bits and a common 3/4 in. wrench or impact driver, crews spend less time sourcing special equipment and more time completing the work.
• Engineered load-transfer efficiency - the undercutting thread design moves load directly into the base material, giving structural professionals confidence that each anchor is working at its full engineered capacity from the moment it is set.

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 provides superior, long-lasting corrosion resistance compared to standard stainless-steel grades, making it ideal for demanding outdoor and marine installations.

Do I need a special drill bit 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, 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, compromising the integrity of the connection.

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

The Titen HD screw anchor can be installed with an impact wrench or by hand tool. A 3/4 in. wrench size is required to drive the hex-washer head, which is designed so that no separate washer is needed for a clean installed appearance.
