The Simpson Titen HD 3/4 in. x 6 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor is a state-of-the-art concrete and masonry screw anchor engineered for structural connections in wet, moist, or damp environments. Built from Type 304 stainless steel and featuring an innovative carbon-steel thread that undercuts the base material as it drives, this heavy-duty anchor delivers fast, efficient installation with long-lasting corrosion resistance - making it a reliable fastening solution for demanding applications where performance and durability cannot be compromised.

Key Features

• Qualified for static and seismic loading conditions - meets the structural demands of both standard and seismic applications, giving engineers and contractors confidence in code-sensitive projects.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes holding strength in concrete and masonry by mechanically engaging the surrounding material for a more secure connection.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - reduces tooling costs and simplifies job-site setup, so crews can get to work without sourcing proprietary equipment.
• Hex-washer head requires no separate washer and provides a clean installed appearance - saves time during installation and delivers a finished, professional look without additional hardware.
• Innovative carbon-steel thread cuts concrete while significantly limiting the amount of carbon steel in the anchor - less carbon steel means less expansion stress on the base material, reducing the risk of cracking near edges or in tight spacing situations.
• Made from Type 304 stainless steel - provides cost-effective corrosion resistance for applications in wet, moist, or damp conditions where a galvanized or plain carbon-steel anchor would be insufficient.
• Installs with an impact wrench or by hand tool using a 1 1/8 in. wrench - compatible with common installation tools already on the job site, keeping workflow fast and flexible.
• Designed for one-time installation only - ensures thread integrity and full rated load capacity are preserved; reinstalling in the same hole can cause excessive thread wear and reduce structural performance.

Why This Product

• Corrosion resistance built for real-world conditions - the Type 304 stainless steel construction is specifically suited for concrete and masonry anchoring where moisture, humidity, or damp exposure is a consistent concern, offering durability that plain steel anchors cannot match in those environments.
• Dual-material thread technology for smarter anchoring - the combination of a stainless steel body with heat-treated carbon-steel cutting threads gives this screw anchor the ability to cut cleanly through concrete and masonry while keeping overall carbon steel content - and the expansion forces that come with it - to a minimum.
• Seismic and static qualification removes guesswork - because this anchor is qualified for both loading conditions, it is suitable for a wider range of structural applications without requiring contractors or engineers to source separate products for different project requirements.
• Straightforward installation with no proprietary tooling - using a standard 3/4 in. ANSI tolerance drill bit and a common 1 1/8 in. wrench or impact driver, this anchor integrates into existing workflows without added complexity or specialized equipment.

Frequently Asked Questions

Can this anchor be removed and reinstalled in the same hole?

No. The Titen HD screw anchor is designed for one-time installation only. Installing the anchor multiple times may result in excessive thread wear and reduce load capacity, which could compromise structural integrity.

What type of drill bit is required to install the THD75600H4SS?

No special drill bit is required. The Titen HD is designed to install using a standard-sized 3/4 in. ANSI tolerance drill bit, which simplifies the installation process and reduces the need for specialized tooling.

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 applications in corrosive or extreme environments such as salt water, or when chemical or corrosive solutions are present.

Is this anchor rated for seismic applications?

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