The Simpson Titen HD 5/8 in. x 6 in. Type 316 Stainless-Steel Heavy-Duty Screw Anchor sets the standard for concrete and masonry anchoring in demanding environments where corrosion resistance cannot be compromised. Engineered with an innovative combination of Type 316 stainless-steel construction and heat-treated carbon-steel cutting threads, this heavy-duty screw anchor delivers fast, efficient installation alongside long-lasting performance in saltwater, chemical-exposure, and other extreme or corrosive conditions - giving contractors and builders unsurpassed peace of mind on every project.

Key Features

• Qualified for static and seismic loading conditions - meets the structural demands of both standard and seismic applications, so you can specify this anchor with confidence on code-sensitive projects.
• Thread design undercuts to efficiently transfer the load to the base material - the undercutting action maximizes load transfer into concrete or masonry, delivering reliable holding strength without relying on expansion pressure alone.
• Innovative carbon-steel cutting threads on a stainless-steel body - the carbon-steel thread cuts cleanly through concrete while minimizing the amount of carbon steel present in the anchor; less carbon steel means less expansion and reduced risk of concrete cracking.
• No special drill bit required - designed for use with a standard 5/8 in. ANSI tolerance drill bit, reducing tooling costs and simplifying the installation process on any job site.
• Hex-washer head requires no separate washer - the integrated hex-washer head speeds up installation and provides a clean, finished appearance without additional hardware.
• Made from Type 316 stainless steel for superior corrosion resistance - Type 316 is the optimal choice for saltwater, marine, chemical, or otherwise corrosive environments where Type 304 would be insufficient.
• Installs with an impact wrench or by hand tool using a 15/16 in. wrench - flexible installation options let crews work efficiently whether power tools are available or not.
• Single-use design - each anchor is engineered for one-time installation; reusing the anchor in the same hole risks excessive thread wear and reduced load capacity, so each anchor delivers its full rated performance when installed correctly.

Why This Product

• Built for the harshest environments - Type 316 stainless steel provides optimal corrosion resistance in saltwater, marine, and chemical-exposure applications where moisture, salt, or corrosive solutions would quickly degrade standard anchors.
• Structural versatility you can count on - qualification for both static and seismic loading conditions means a single anchor solution covers a wide range of structural anchoring requirements in concrete and masonry, reducing the need to source multiple products for different project conditions.
• Faster installation without sacrificing performance - compatibility with standard ANSI tolerance drill bits and the ability to drive with either an impact wrench or a hand tool means fewer specialized tools on site and less time spent per anchor, without compromising load capacity.
• Proven Simpson engineering with a clean finished look - the integrated hex-washer head eliminates the need for a separate washer, streamlining the installation process and producing a professional appearance that meets the standards expected of Simpson anchoring solutions.

Frequently Asked Questions

Can the Titen HD screw anchor be removed and reinstalled in the same hole?

No. The Titen HD screw anchor is designed for one-time use only. Installing the anchor multiple times in the same hole may result in excessive thread wear and reduce the anchor's load capacity, compromising structural integrity.

What type of drill bit is required to install this anchor?

No special drill bit is required. The Titen HD 5/8 in. anchor is designed to install using a standard 5/8 in. ANSI tolerance drill bit, which simplifies the installation process and reduces the need for specialized tooling.

Why choose Type 316 stainless steel over Type 304 for this anchor?

Type 316 stainless steel is the optimal choice for applications in corrosive or extreme environments, such as saltwater exposure or where chemical or corrosive solutions are present. Type 304 is a cost-effective solution for less extreme applications where the environment may simply be wet, moist, or damp.

What tools are needed to install the Titen HD THDB62600H6SS?

The anchor installs with either an impact wrench or a hand tool. A 15/16 in. wrench size is required to drive the hex-washer head, and the recommended fixture hole size is 3/4 in. to 13/16 in.
