The Simpson Titen HD 5/8 in. x 6 in. Type 304 Stainless-Steel Heavy-Duty Screw Anchor delivers reliable, long-lasting performance in concrete and masonry applications where the environment may be wet, moist, or damp. Combining the corrosion resistance of Type 304 stainless steel with an innovative heat-treated carbon-steel cutting thread, this screw anchor provides fast and efficient installation without sacrificing holding strength. Its state-of-the-art undercutting thread design efficiently transfers load to the base material, making it a trusted solution for structural anchoring in demanding conditions.

Key Features

• Qualified for static and seismic loading conditions - gives buyers confidence that this heavy-duty screw anchor meets performance requirements in seismically active regions as well as standard structural applications.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes holding strength in concrete and masonry so the anchor performs reliably under demanding loads.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - saves time and eliminates the cost of sourcing specialty tooling, keeping installation straightforward.
• Innovative carbon-steel cutting thread limits the amount of carbon steel in the anchor - less carbon steel means less expansion during installation, reducing stress on the base material and lowering the risk of cracking.
• Hex-washer head requires no separate washer - simplifies installation and delivers a clean, finished appearance without additional hardware.
• Installs with an impact wrench or by hand tool using a 15/16 in. hex wrench - offers flexibility on the job site, letting crews work efficiently with the tools they already have.
• Single-use design - the anchor is engineered for one-time installation; reinstalling it may cause excessive thread wear and reduce load capacity, so buyers should plan anchor placement carefully before driving.

Why This Product

• Built-in corrosion resistance for wet and damp environments - Type 304 stainless-steel construction provides a cost-effective solution for applications where moisture exposure is a concern, extending the service life of the installation without the premium cost of Type 316.
• Dual-material innovation delivers cutting performance without compromising anchor integrity - the carbon-steel cutting threads handle the hard work of undercutting concrete while keeping the overall carbon-steel content low, striking the right balance between installation ease and long-term corrosion resistance.
• Seismic qualification removes guesswork for code-sensitive projects - with approval for both static and seismic loading, this anchor is suitable for a wider range of structural applications and helps contractors meet code requirements without switching products.
• Streamlined installation reduces labor time and material costs - standard ANSI tolerance drill bits, a simple hex-washer head, and compatibility with common impact wrenches or hand tools mean fewer steps, fewer accessories, and faster completion on the job site.

Frequently Asked Questions

Can the Titen HD screw anchor be used in 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 anchoring performance under dynamic loads is critical.

What drill bit size is required to install the THDB62600H4SS?

No special drill bit is required. The Titen HD screw anchor is designed to install using standard-sized ANSI tolerance drill bits, with a 5/8 in. hole diameter. A 15/16 in. hex wrench is used to drive the anchor using an impact wrench or hand tool.

Why is Type 304 stainless steel used for this anchor, and when should I choose Type 316 instead?

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

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, compromising the integrity of the connection.
