The Simpson Titen HD 3/4 in. x 5 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor is a premium concrete and masonry anchoring solution engineered specifically for corrosive, extreme, and demanding environments. Built from Type 316 stainless steel and featuring an innovative heat-treated carbon-steel cutting thread, this heavy-duty screw anchor delivers the fast, efficient installation contractors expect alongside the long-lasting corrosion resistance required in salt water exposure, coastal applications, and settings where chemical or corrosive solutions are present.

Key Features

• Qualified for static and seismic loading conditions - meets the structural demands of code-sensitive projects and earthquake-zone installations, giving you confidence across a wide range of applications.
• Undercutting thread design - efficiently transfers load directly to the base material, resulting in a stronger, more reliable connection in concrete and masonry.
• No special drill bit required - installs 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, streamlining installation and delivering a clean, finished appearance once set.
• Innovative carbon-steel cutting thread on a stainless body - the carbon-steel thread cuts concrete effectively while minimizing the total amount of carbon steel in the anchor, which means less expansion and reduced risk of concrete cracking.
• Type 316 stainless steel construction - provides superior corrosion resistance over standard stainless grades, making this anchor the optimal choice for salt water, coastal, and chemically harsh environments.
• Single-use design by engineering intent - reinstalling the anchor multiple times can cause excessive thread wear and reduce load capacity, so each anchor is engineered to perform at its rated capacity on the first and only installation.

Why This Product

• Purpose-built for the harshest conditions - Type 316 stainless steel is the optimal material choice when chemical exposure, salt water, or persistently corrosive environments would cause standard anchors to fail prematurely, giving this anchor a clear advantage in marine, coastal, and industrial settings.
• Seismic and static qualification in one anchor - rather than sourcing different hardware for different load scenarios, this screw anchor is qualified for both static and seismic conditions, reducing complexity and supporting code compliance on demanding structural projects.
• Faster installation without special tooling - compatibility with standard ANSI tolerance drill bits and a 1 1/8 in. hex drive that accepts an impact wrench or hand tool means less setup time and no extra equipment to source or carry to the job site.
• Proven Simpson engineering in a stainless package - the same undercutting thread technology trusted for heavy-duty concrete anchoring is now combined with the corrosion resistance of 316 stainless steel, making this anchor a dependable long-term solution where both strength and durability are non-negotiable.

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 salt water, or when chemical or corrosive solutions are present. It provides superior corrosion resistance compared to other stainless steel grades, making it ideal for harsh and demanding job sites.

Can the Titen HD screw anchor be removed and reinstalled?

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.

What drill bit and tools are needed to install this anchor?

No special drill bit is required. The anchor is designed to install using standard-sized ANSI tolerance drill bits sized at 3/4 in. It can be installed with an impact wrench or by hand tool using a 1-1/8 in. wrench.

Is this anchor approved for seismic applications?

Yes. The Simpson THD75500H6SS Titen HD screw anchor is qualified for both static and seismic loading conditions, making it suitable for use in seismically active regions and code-compliant structural applications.
