The Simpson Titen HD 3/8 in. x 3 in. Type 304 Stainless-Steel Heavy-Duty Screw Anchor is a premium concrete and masonry screw anchor engineered for reliable performance in wet, moist, or damp environments where corrosion resistance is a must. Built from Type 304 stainless steel and paired with an innovative heat-treated carbon-steel cutting thread, this anchor delivers fast, efficient installation alongside long-lasting durability - making it a dependable choice for both static and seismic loading applications in general construction.

Key Features

• Qualified for static and seismic loading conditions - meets the demands of a wide range of structural applications, giving you confidence the anchor will perform whether loads are steady or dynamic.
• Undercutting thread design - efficiently transfers load directly to the base material for a secure, high-strength connection in concrete and masonry.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits, reducing tool costs and simplifying job-site prep.
• Hex-washer head - eliminates the need for a separate washer, speeding up installation and leaving a clean, professional finished appearance.
• Innovative carbon-steel cutting thread on a stainless-steel body - the carbon-steel thread cuts efficiently through concrete while minimizing the amount of carbon steel present in the anchor, which means less expansion and reduced risk of cracking the base material.
• Installs with an impact wrench or hand tool - compatible with common installation methods, so crews can work efficiently with equipment already on hand.
• Single-use design - installing the anchor one time only preserves thread integrity and maintains full rated load capacity; reinstalling may cause excessive thread wear and reduce performance.

Why This Product

• Corrosion resistance without the premium price of Type 316 - Type 304 stainless steel provides meaningful protection against moisture, humidity, and damp conditions, making it a cost-effective solution for projects that do not involve extreme or highly corrosive environments such as salt water exposure.
• Seismic and static qualification in one anchor - rather than sourcing separate fasteners for different loading scenarios, this screw anchor covers both static and seismic conditions, simplifying procurement and ensuring code-compliance confidence across a broader range of job types.
• Straightforward installation with no specialty tooling - compatibility with standard ANSI tolerance drill bits and common hand or impact tools means there is no learning curve, no added equipment expense, and no slowdown on the job site.
• Designed for concrete and masonry versatility - whether the application involves poured concrete or masonry substrates, this heavy-duty screw anchor is built to handle both, reducing the need to stock multiple anchor types for different base materials.

Frequently Asked Questions

What base materials is the Titen HD screw anchor designed for?

The Titen HD stainless-steel screw anchor is designed for installation in concrete and masonry base materials, making it versatile for a wide range of construction and anchoring applications.

Can the Titen HD anchor be reused or installed multiple times?

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. It is a single-use anchor.

What drill bit is required to install the THD37300H4SS?

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