The Simpson Titen HD 1/4 in. x 2 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor is a state-of-the-art fastening solution engineered for concrete and masonry installations where corrosion resistance and structural reliability are non-negotiable. Built from Type 316 stainless steel - the optimal material for applications exposed to salt water, marine environments, and chemical or corrosive solutions - this screw anchor pairs superior corrosion protection with an innovative heat-treated carbon-steel thread design that undercuts the base material for efficient, high-strength load transfer. Whether the job involves static loading or seismic conditions, this anchor delivers fast installation and long-lasting performance in the most demanding environments.

Key Features

• Qualified for static and seismic loading conditions - meets the structural demands of both everyday and code-critical applications, giving contractors confidence on projects with strict engineering requirements.
• Undercutting thread design - efficiently transfers load to the base material for a stronger, more reliable hold in concrete and masonry substrates.
• No special drill bit required - designed to work with standard-sized ANSI tolerance drill bits, so there is no need for additional tooling or extra setup time on the job site.
• Hex-washer head design - eliminates the need for a separate washer, simplifying installation and delivering a clean, finished appearance once set.
• Innovative carbon-steel cutting threads on a stainless steel body - the cutting threads effectively engage concrete while minimizing the amount of carbon steel in the anchor, which reduces expansion forces and helps protect surrounding material.
• Type 316 stainless steel construction - provides superior corrosion resistance in extreme environments including salt water exposure and installations where chemical or corrosive solutions are present, outperforming standard stainless options in the harshest conditions.
• Single-use design - the anchor is engineered for one-time installation; reinstalling a used anchor risks excessive thread wear and reduced load capacity, so each anchor delivers its full rated performance when used as intended.
• Installs with an impact wrench or by hand tool - flexibility in installation method allows crews to work efficiently with the tools already on hand.

Why This Product

• Built for the most corrosive job site conditions - Type 316 stainless steel is the correct specification for marine, salt water, and chemically exposed environments where lesser materials would fail prematurely, making this anchor a long-term solution rather than a short-term fix.
• Engineered for speed without sacrificing strength - the undercutting thread design and compatibility with standard ANSI tolerance drill bits mean faster installation cycles with no extra tooling, reducing labor time on concrete and masonry anchor work.
• Dual-material thread technology protects the structure - by combining stainless steel construction with carbon-steel cutting threads that minimize expansion forces, this anchor reduces stress on the surrounding concrete during installation, a meaningful advantage in precision or sensitive structural applications.
• Seismic and static qualification adds design flexibility - with approval for both seismic and static loading conditions, this screw anchor supports a wider range of project specifications and gives engineers and contractors a single trusted fastener for varied structural demands.

Frequently Asked Questions

What makes the Type 316 stainless steel version preferable over Type 304 for certain jobs?

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. Type 304 is a cost-effective solution for less extreme applications where the environment may be wet, moist, or damp.

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.

Do I need a special drill bit to install this 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.

What tools are needed to install the THDC25200H6SS, and is a separate washer required?

The anchor installs with an impact wrench or by hand tool using a 3/8 in. wrench size. The hex-washer head design requires no separate washer and provides a clean installed appearance.
