The Simpson Titen HD 3/8 in. x 2-1/2 in. Countersunk Head Heavy-Duty Screw Anchor in Type 316 Stainless Steel delivers high-performance anchoring in cracked and uncracked concrete and masonry, purpose-built for environments where corrosion resistance cannot be compromised. The countersunk head profile sits flush with the surface after installation, making it the right choice for exposed through-set applications and anywhere a clean, low-profile finish is required. With a T50 6-lobe drive, serrated cutting tip, and compatibility with standard ANSI tolerance drill bits, this heavy-duty concrete screw anchor is engineered to install quickly and reliably - whether the application involves static loads, seismic conditions, or wind-governed structural demands.

Key Features

• Type 316 stainless steel construction - provides severe-level corrosion resistance, making this anchor well-suited for moisture-exposed, chemical-prone, or other demanding outdoor and coastal environments where carbon steel would degrade.
• Qualified for static and seismic loading conditions - gives engineers and contractors the confidence to specify this anchor on code-sensitive projects where performance under dynamic loads must be documented.
• Countersunk head design - allows the anchor to sit flush with or below the fixture surface, enabling clean flush-mount installations that a hex head anchor cannot achieve.
• T50 6-lobe drive - reduces driver-bit cam-outs during installation compared to traditional recessed head styles, resulting in faster driving and less bit wear on the job.
• Serrated teeth on the anchor tip - facilitate cutting into concrete or masonry as the anchor is driven, reducing installation torque and making the process easier on the installer and the tool.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits at the same 3/8 in. diameter as the anchor, eliminating the need for specialty tooling and keeping job-site setup simple.
• Removable after installation - ideal for temporary anchoring applications or situations where attached fixtures may need to be repositioned or replaced at a later date.
• Driver bit included in each box - means the correct installation tool is on hand immediately, with no separate purchase required to get started.

Why This Product

• Built for corrosive environments where standard anchors fall short - the Type 316 stainless steel version of the Titen HD is specifically intended for applications exposed to moisture, chemicals, or other corrosive conditions that would compromise a carbon steel anchor over time, offering long-lasting durability without the need for frequent replacement.
• Flush-mount capability opens up applications hex head anchors cannot handle - the countersunk head style makes this screw anchor practical for exposed through-set connections and surface-critical installations where a protruding head is not acceptable.
• Simplifies installation without sacrificing performance - standard ANSI drill bit compatibility, a 6-lobe drive that resists cam-out, and serrated cutting teeth all work together to make this a straightforward anchor to install correctly, reducing the margin for error on demanding structural connections.
• Flexibility to anchor temporary or adjustable fixtures - because the Titen HD is fully removable, it suits applications where the anchored fixture may need to move, making it a practical choice across a broader range of concrete and masonry fastening scenarios than a non-removable anchor would allow.

Frequently Asked Questions

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

The Titen HD heavy-duty screw anchor is designed for use in cracked and uncracked concrete, as well as masonry applications.

Why choose the Type 316 stainless steel version over the carbon steel Titen HD?

The Type 316 stainless steel option provides severe-level corrosion resistance, making it the preferred choice for environments exposed to moisture, chemicals, or other corrosive conditions where long-lasting durability is required. The carbon steel version is designed for dry, interior, noncorrosive environments or temporary outdoor applications.

Can the Titen HD countersunk anchor be removed after installation?

Yes. The Titen HD is removable, making it ideal for temporary anchoring or applications where fixtures may need to be relocated or adjusted after installation.

What drill bit size is required to install this anchor?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits with a 3/8 in. diameter - the same size as the anchor itself.
