The Simpson Titen HD 5/8 in. x 4 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor is a state-of-the-art concrete and masonry anchoring solution engineered for demanding environments where long-term corrosion resistance is non-negotiable. Combining the proven durability of Type 316 stainless steel with an innovative heat-treated carbon-steel cutting thread design, this heavy-duty screw anchor delivers fast, efficient installation alongside the reliability required for static and seismic loading conditions - making it the go-to choice for marine, coastal, chemical-exposure, and other corrosive or extreme applications.

Key Features

• Qualified for static and seismic loading conditions - gives you confidence that the anchor meets the structural demands of both everyday and high-stress applications, including seismic zones.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes holding strength in concrete and masonry by directing force directly into the substrate where it matters most.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - reduces setup time and eliminates the cost of sourcing proprietary tooling, so your crew can get to work faster.
• Hex-washer head requires no separate washer - simplifies the installation process and delivers a clean, professional finished appearance without additional hardware.
• Innovative carbon-steel thread that effectively cuts the concrete while significantly limiting the amount of carbon steel in the anchor - less carbon steel means less expansion stress on the base material, reducing the risk of cracking near edges or in tighter spacing situations.
• Made from Type 316 stainless steel - provides superior, long-lasting corrosion resistance in salt water, marine, and chemical environments where standard anchors would deteriorate prematurely.
• Installs with an impact wrench or by hand tool using a 15/16 in. wrench - offers installation flexibility whether working in tight spaces or on open jobsites.
• Single-use design - the anchor is engineered for one-time installation; reusing it risks excessive thread wear and reduced load capacity, so each anchor delivers its full rated performance when installed correctly the first time.

Why This Product

• Built for the harshest environments - Type 316 stainless steel is the optimal material choice when anchoring in salt water, marine settings, or locations where chemical or corrosive solutions are present, offering a higher level of protection than standard stainless grades.
• Seismic and static load qualification in one anchor - rather than sourcing different anchors for different loading scenarios, this single screw anchor covers both static and seismic conditions, streamlining procurement and ensuring code-compliant performance across a wider range of projects.
• Fast installation with no specialty tooling - compatibility with standard ANSI tolerance drill bits and a common 15/16 in. wrench means no special equipment purchases, keeping projects on schedule and within budget.
• Trusted Simpson engineering - the Titen HD line is a recognized heavy-duty screw anchor solution from Simpson, a brand synonymous with structural reliability, giving engineers, contractors, and inspectors a well-documented product to specify and approve with confidence.

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 those involving salt water or the presence of chemical or corrosive solutions. It provides superior, long-lasting corrosion resistance compared to standard stainless steel grades.

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.

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.

Is this anchor approved for seismic applications?

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