The Simpson Titen HD 1/2 in. x 4 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor is engineered for concrete and masonry fastening applications where corrosion resistance and structural reliability are non-negotiable. Built from Type 304 stainless steel and featuring an innovative heat-treated carbon-steel cutting thread, this heavy-duty screw anchor delivers fast, efficient installation alongside long-lasting performance in wet, moist, or damp conditions - giving contractors and builders genuine peace of mind on every project.

Key Features

• Qualified for static and seismic loading conditions - meets the demands of structurally critical applications, giving you confidence the anchor will perform under both everyday and dynamic loads
• Undercutting thread design efficiently transfers load to the base material - maximizes holding strength in concrete and masonry so the connection performs as intended
• Innovative carbon-steel cutting thread with limited carbon-steel content - the thread cuts cleanly through concrete while minimizing expansion forces, reducing the risk of edge or spacing failures
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, so you can get to work immediately without sourcing specialized tooling
• Hex-washer head requires no separate washer - eliminates an extra component, speeds up installation, and leaves a clean, professional finished appearance
• Installs with an impact wrench or by hand tool using a 3/4 in. wrench - compatible with common jobsite tools for flexible, efficient installation in the field
• Single-use design - the anchor is intended for one-time installation; reinstalling may cause excessive thread wear and reduce load capacity, so plan placement carefully before driving

Why This Product

• Corrosion resistance engineered for real-world conditions - Type 304 stainless steel construction makes this anchor a cost-effective, reliable choice for applications in wet, moist, or damp environments where standard carbon-steel anchors would degrade over time
• Seismic and static load qualification in one anchor - rather than sourcing different fasteners for different structural scenarios, this single screw anchor is tested and qualified for both loading conditions, simplifying specification and procurement
• Streamlined installation with no special tooling - compatibility with standard ANSI tolerance drill bits and common hand or impact-drive tools means faster setup, fewer delays, and lower overall installed cost on any concrete or masonry project
• A stainless steel solution where Type 316 would be overkill - for projects in damp or moist environments that do not involve saltwater, chemical exposure, or extreme corrosive conditions, Type 304 delivers appropriate corrosion protection at a more practical price point

Frequently Asked Questions

What base materials is the Titen HD stainless steel screw anchor compatible with?

The Titen HD stainless steel screw anchor is designed for use in concrete and masonry base materials, making it suitable for a wide variety of structural and fastening applications.

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, streamlining 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 its load capacity.

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

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