The Simpson Titen HD 1/4 in. x 2-3/4 in. Countersunk Head Heavy-Duty Screw Anchor is a carbon steel concrete and masonry screw anchor built for demanding structural fastening applications where both performance and installation simplicity matter. Designed for use in dry, interior, noncorrosive environments or temporary outdoor applications, it delivers reliable holding strength in cracked and uncracked concrete and masonry under static, seismic, and wind-governed conditions. The countersunk head profile enables flush-mount and through-set installations where a standard hex head would be impractical, and the T30 6-lobe drive system keeps the installation process clean and efficient from start to finish.

Key Features

• Qualified for static and seismic loading conditions - meets the structural demands of seismic and wind-governed construction, giving installers confidence in high-stakes anchoring applications.
• Hole size matches anchor size (1/4 in.) - standard fractional sizing means no guesswork on drill selection and a more straightforward, predictable installation process.
• Compatible with standard ANSI tolerance drill bits - no special tooling required, reducing setup time and keeping the job moving without sourcing proprietary accessories.
• Removable after installation - ideal for temporary anchoring or fixtures that may need to be repositioned, adding flexibility that permanent anchor solutions cannot offer.
• T30 6-lobe drive reduces cam-out during driving - the 6-lobe geometry grips the driver bit more securely than traditional recessed heads, making installation easier and reducing the risk of bit slippage or stripped fasteners.
• Countersunk head enables flush-mount profiles - allows the anchor to sit level with or below the fixture surface, producing a cleaner appearance in exposed through-set applications where a protruding head is not acceptable.
• Serrated tip teeth cut into the base material during installation - reduces the torque required to drive the anchor, easing the effort needed and speeding up installation in concrete and masonry.
• Driver bit included in each box - the correct T30 drive bit ships with the anchors, so installers have everything needed on hand without a separate trip for hardware.
• Zinc-plated finish - provides a base level of corrosion resistance suitable for dry, interior, or temporary outdoor use; not intended for permanent exterior or highly corrosive environments, keeping expectations clear upfront.

Why This Product

• One anchor, two critical load qualifications - the Titen HD carries qualification for both static and seismic loading conditions, making it a versatile choice for structural concrete and masonry fastening in regions with strict building code requirements, without needing separate anchors for different load scenarios.
• Flush-mount capability opens up applications hex heads cannot - the countersunk head design is purpose-built for installations that demand a low-profile or fully flush surface finish, whether for aesthetic reasons or clearance requirements that a standard hex head anchor simply cannot accommodate.
• Simpler installation with no specialty tooling - the combination of standard ANSI-compatible drill bits, a same-as-anchor hole size, serrated cutting tip, and an included driver bit removes nearly every common friction point from the installation process, saving time on the job site.
• Removability gives installers long-term flexibility - unlike adhesive or expansion anchors that are permanent once set, the Titen HD screw anchor can be removed and reused in scenarios where fixtures need to be relocated or adjusted, making it a practical choice for temporary structures or evolving layouts.

Frequently Asked Questions

What type of base material is the Titen HD THDB25234CS designed for?

The Titen HD is designed for use in cracked and uncracked concrete as well as masonry. It is intended for dry, interior, noncorrosive environments or temporary outdoor applications, and is not recommended for permanent exterior use or highly corrosive environments.

Do I need a special drill bit to install this anchor?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits. The hole size is the same as the anchor size - 1/4 in. - making installation straightforward without additional tooling.

Why is a countersunk head style used on this anchor?

The countersunk head style is for applications that require a flush-mount profile. Countersinking also leaves a cleaner surface appearance for exposed through-set applications, making it suitable for situations where a hex head would not allow for a flush finish.

Can the Titen HD be removed after installation?

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