The Simpson Titen HD 3/8 in. x 2-1/2 in. Countersunk Head Heavy-Duty Screw Anchor is a high-performance carbon steel screw anchor engineered for structural and mechanical fastening in cracked and uncracked concrete and masonry. The countersunk head delivers a flush-mount, low-profile finish that works in applications where a hex head simply cannot, while the T50 6-lobe drive system and serrated cutting tip make installation faster and more reliable. Zinc-plated for use in dry, interior, noncorrosive environments or temporary outdoor applications, this anchor is qualified for both static and seismic loading conditions, meeting the demands of wind-governed structural work and general construction fastening alike.

Key Features

• Qualified for static and seismic loading conditions - meets structural requirements for high-load and seismic applications, giving you confidence in code-sensitive installations.
• Countersunk head design - allows for flush-mount and through-set applications where a low-profile surface appearance is required, delivering a cleaner finished look that a hex head cannot achieve.
• T50 6-lobe drive - reduces driver-bit cam-outs compared to traditional recessed anchor heads, so installation goes faster with less frustration and fewer stripped drives.
• Serrated teeth on the anchor tip - facilitate cutting into the base material and reduce installation torque, making it easier to drive the anchor to full depth.
• Standard fractional sizing with same-size drill bit - the 3/8 in. anchor uses a standard 3/8 in. ANSI tolerance drill bit, so no special tooling is needed on the job site.
• Removable anchor design - ideal for temporary anchoring or applications where fixtures may need to be relocated in the future, reducing long-term commitment to a fixed layout.
• Zinc-plated carbon steel finish - suitable for dry, interior, noncorrosive environments or temporary outdoor use; not recommended for permanent exterior or highly corrosive environments, so you can match the right anchor to the right job.
• Driver bit included in each box - eliminates the need to source a compatible bit separately, keeping your crew moving without interruption.

Why This Product

• One anchor, two critical load conditions - the Titen HD is qualified for both static and seismic loading, making it a reliable single solution for projects in seismic and wind-governed regions rather than requiring separate products for different conditions.
• Flush-mount capability opens up more applications - the countersunk head sits flush with or below the fixture surface, enabling clean through-set concrete and masonry installations that are simply not possible with a standard hex head anchor.
• Simplified installation with standard tooling - because the hole size matches the anchor size and no special drill bits are required, crews can use existing ANSI tolerance bits, saving time and reducing job site complexity.
• Reusable and removable by design - unlike adhesive or expansion anchors that are difficult or impossible to remove, the Titen HD screw anchor can be taken out and reinstalled, making it a practical choice for temporary structures, equipment pads, or any fixture that may need to move.

Frequently Asked Questions

What base materials is the Titen HD THD37212CS approved for use in?

The Titen HD heavy-duty screw anchor is designed for use in cracked and uncracked concrete as well as masonry substrates, making it suitable for a wide range of structural anchoring applications.

Can the Titen HD countersunk anchor be used outdoors permanently?

No. Because the THD37212CS is zinc plated carbon steel, it is not recommended for permanent exterior use or highly corrosive environments. It is suitable for dry, interior, noncorrosive environments or temporary outdoor applications only.

Does the countersunk head style offer any advantage over a standard hex head anchor?

Yes. The countersunk head allows for flush-mount applications that are not possible with a hex head, and countersinking also leaves a cleaner surface appearance for exposed through-set applications where a low-profile finish is required.

Is the Titen HD screw anchor removable after installation?

Yes. The Titen HD is removable, making it ideal for temporary anchoring or applications where fixtures may need to be repositioned or moved in the future.
