The Simpson Titen HD 5/8 in. x 6-1/2 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor is a state-of-the-art concrete and masonry anchoring solution engineered for installations where moisture, dampness, or wet conditions demand reliable, long-lasting corrosion resistance. It combines the proven durability of Type 304 stainless steel with an innovative heat-treated carbon-steel cutting thread that undercuts the base material for efficient load transfer - delivering fast, dependable performance in structural connections subject to both static and seismic loading conditions.

Key Features

• Qualified for static and seismic loading conditions - gives contractors and engineers confidence that the anchor meets demands for a wide range of structural applications, including those governed by seismic design requirements.
• Undercutting thread design efficiently transfers load to the base material - maximizes holding strength in concrete and masonry by mechanically engaging the substrate, reducing reliance on friction or expansion alone.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, saving time and eliminating the need for dedicated tooling on the job site.
• Hex-washer head requires no separate washer - simplifies installation and delivers a clean, finished appearance without additional hardware.
• Innovative carbon-steel cutting thread with minimal carbon-steel content - effectively cuts through concrete while significantly limiting the amount of carbon steel in the anchor, meaning less expansion and reduced risk of stress cracking in the base material.
• Type 304 stainless steel construction - provides cost-effective corrosion resistance for wet, moist, or damp environments where extreme chemical exposure is not a primary concern.
• Single-use design - the anchor is intended for one-time installation only; reinstalling may cause excessive thread wear and reduce load capacity, so plan placement carefully before driving.
• Installs with an impact wrench or hand tool using a 15/16 in. wrench - compatible with common jobsite tools, keeping installation straightforward and efficient.

Why This Product

• Built for corrosive environments without the premium cost of Type 316 - Type 304 stainless steel delivers meaningful protection against moisture and dampness, making it a practical, cost-effective upgrade over standard carbon-steel screw anchors for outdoor, humid, or wet-area concrete anchoring.
• Seismic and static qualification in one anchor - rather than sourcing separate fasteners for different load cases, this heavy-duty screw anchor satisfies both static and seismic requirements, streamlining specification and procurement on code-sensitive projects.
• Faster installation with no specialty tooling - compatibility with standard ANSI tolerance drill bits and common wrenching tools means crews can set anchors quickly without carrying extra equipment, reducing labor time on concrete and masonry fastening tasks.
• Engineered load transfer through undercutting threads - the cutting thread geometry actively engages the base material rather than relying on expansion, providing a mechanically efficient connection that supports confidence in long-term structural performance.

Frequently Asked Questions

Can the Titen HD screw anchor be removed and reinstalled?

No. Use a Titen HD screw anchor one time only - installing the anchor multiple times may result in excessive thread wear and reduce load capacity.

Does this anchor require a special drill bit for installation?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits, simplifying the installation process.

What is the difference between Type 304 and Type 316 stainless steel 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 or when chemical or corrosive solutions are present.

Is this anchor rated for seismic applications?

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