The Simpson Titen HD 3/8 in. x 6 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor is engineered for concrete and masonry applications where corrosion resistance cannot be compromised. Built from Type 316 stainless steel and featuring an innovative heat-treated carbon-steel thread design, this heavy-duty screw anchor delivers fast, efficient installation alongside long-lasting durability in the most demanding environments - including salt water exposure, marine settings, and applications where chemical or corrosive solutions are present.

Key Features

• Qualified for static and seismic loading conditions - meets code requirements for both everyday structural loads and seismic applications, giving engineers and contractors confidence in high-accountability installations.
• Undercutting thread design - efficiently transfers load directly to the base material, maximizing holding strength in concrete and masonry without relying on expansion force.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits, reducing tool costs and simplifying job-site preparation.
• Hex-washer head design - eliminates the need for a separate washer and provides a clean, finished appearance once installed.
• Innovative carbon-steel cutting threads on a stainless body - the carbon-steel thread effectively cuts concrete while minimizing the total amount of carbon steel in the anchor, meaning less expansion stress and more precise seating.
• Type 316 stainless steel construction - provides superior corrosion resistance compared to standard stainless grades, making this anchor the optimal choice for salt water, marine, chemical, and other extreme environments.
• Single-use design - installing the anchor one time only preserves full thread integrity and rated load capacity; reinstallation can cause excessive thread wear and reduce performance.
• Installs with an impact wrench or hand tool - compatible with a 9/16 in. wrench, allowing flexible installation with commonly available equipment.

Why This Product

• Built for the harshest environments - Type 316 stainless steel is the optimal grade for salt water, marine, and chemically aggressive environments, making this anchor a reliable long-term solution where lesser materials would corrode and fail.
• Seismic and static qualification in one anchor - rather than sourcing separate products for different load conditions, this single screw anchor is qualified for both static and seismic applications, streamlining procurement and ensuring code compliance across a range of projects.
• Faster installation without specialized tooling - standard ANSI tolerance drill bits and a common 9/16 in. wrench or impact driver are all that is needed, reducing setup time and keeping crews moving efficiently on the job site.
• Proven load transfer technology - the undercutting thread design mechanically engages the base material rather than relying on friction or expansion alone, delivering dependable holding strength in concrete and masonry anchoring applications.

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 corrosion resistance compared to other stainless steel grades, ensuring long-lasting performance in demanding conditions.

Can this anchor be installed and removed multiple times?

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. It is designed for a single installation to maintain its full structural integrity and rated performance.

Do I need a special drill bit or wrench to install this anchor?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits. Installation is performed with a 9/16 in. wrench, and the anchor can be driven using an impact wrench or by hand tool.

Is this anchor approved for seismic applications?

Yes. The Titen HD screw anchor is qualified for both static and seismic loading conditions, making it a reliable choice for structural applications in areas subject to seismic activity.
