The Simpson Titen HD 5/8 in. x 5 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 corrosion resistance of Type 316 stainless steel with an innovative heat-treated carbon-steel cutting thread, delivering fast and efficient installation alongside long-lasting performance in the most demanding conditions - including saltwater exposure and applications where chemical or corrosive solutions are present. Whether you are anchoring into concrete or masonry in a marine environment, an industrial setting, or any corrosive outdoor application, the Simpson Titen HD screw anchor provides unsurpassed peace-of-mind.

Key Features

• Qualified for static and seismic loading conditions - meets the structural demands of both everyday and high-risk installations, giving you confidence the anchor will perform when it matters most.
• 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 working with tools you already own, with no additional accessories to source.
• Hex-washer head requires no separate washer - simplifies installation and delivers a clean, finished appearance without extra hardware.
• Innovative carbon-steel thread effectively cuts concrete while significantly limiting the amount of carbon steel in the anchor - less carbon steel means less expansion and a more precise, reliable fit in the base material.
• Made from Type 316 stainless steel - the optimal material choice for saltwater, marine, and chemically corrosive environments, providing superior corrosion resistance where lesser grades would fail.
• Installs with an impact wrench or by hand tool using a 15/16 in. wrench - offers installation flexibility across job sites whether power tools are available or not.
• Single-use anchor design - installing the anchor one time only preserves full thread integrity and rated load capacity, ensuring your installation meets its engineered performance specifications.

Why This Product

• Purpose-built for harsh and corrosive environments - Type 316 stainless steel is the optimal choice when saltwater exposure, chemical solutions, or extreme outdoor conditions are present, making this anchor a reliable long-term solution where standard anchors would corrode and fail.
• No compromise between corrosion resistance and cutting performance - the hybrid design pairs stainless-steel construction with heat-treated carbon-steel cutting threads, so you get the durability of premium stainless steel without sacrificing the thread-cutting efficiency needed for concrete and masonry applications.
• Seismic and static load qualification removes guesswork - for contractors and engineers working on projects with strict structural requirements, the Titen HD is qualified for both static and seismic loading conditions, supporting code-compliant installations with confidence.
• Straightforward installation with standard tools - because no special drill bits or additional washers are required, the Titen HD screw anchor reduces prep time and keeps your job site efficient without adding complexity or cost to the fastening process.

Frequently Asked Questions

What makes Type 316 stainless steel the right choice for this anchor?

Type 316 is the optimal choice for applications in corrosive or extreme environments such as saltwater, or when chemical or corrosive solutions are present. It provides superior corrosion resistance compared to other stainless-steel grades, making it ideal for the most demanding installation environments.

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 at a 5/8 in. diameter, making installation straightforward without the need for specialty 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 its load capacity, which could compromise the integrity of the connection.

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

The anchor installs with an impact wrench or by hand tool. A 15/16 in. wrench size is required. The hex-washer head design eliminates the need for a separate washer and provides a clean installed appearance upon completion.
