The Simpson Titen HD 3/8 in. x 6 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for optimum performance in both cracked and uncracked concrete and masonry. Its self-undercutting, non-expansion design has been tested and shown to provide outstanding structural reliability under static and seismic loading conditions, making it a dependable choice for structural anchoring applications even at reduced edge distances and spacings. Zinc-plated for corrosion resistance in appropriate environments, this heavy-duty concrete screw anchor combines installation simplicity with the load-transfer performance that demanding structural work requires.

Key Features

• Qualified for static and seismic loading conditions - engineered and tested to meet the performance demands of both standard structural and seismic anchoring applications, giving contractors confidence in safety-critical installations.
• Self-undercutting thread design - the threads undercut into the base material to efficiently transfer the load to the concrete or masonry, providing strong, reliable holding power without an expansion sleeve.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits, reducing tool requirements and simplifying the installation process on the job site.
• Hex-washer head design - requires no separate washer, streamlining installation while delivering a clean, finished appearance once the anchor is set.
• Specialized heat-treating process - creates tip hardness for better cutting into concrete and masonry without compromising the ductility of the anchor body, supporting both performance and structural integrity.
• Zinc-plated carbon steel construction - suitable for permanent dry, interior non-corrosive environments and can also be used for temporary exterior applications where a robust, corrosion-resistant finish is needed.
• Single-use design - the Titen HD screw anchor is intended for one-time installation only; reinstalling the anchor may cause excessive thread wear and reduce load capacity, so proper placement the first time is essential.

Why This Product

• Versatile performance in cracked and uncracked concrete - unlike anchors limited to uncracked substrates, the Titen HD is specifically designed and tested for optimum performance in both cracked and uncracked concrete, expanding its suitability across a wider range of structural anchoring scenarios.
• Structural-grade reliability at tight spacings - the non-expansion, self-undercutting design makes this heavy-duty screw anchor ideal for structural applications even at reduced edge distances and spacings, where many traditional expansion anchors cannot be used.
• Fast, straightforward installation - with no special drill bit required and a hex-washer head that eliminates the need for a separate washer, the Titen HD is built to save time and reduce complexity on concrete and masonry anchoring jobs.
• Seismic-tested for code-sensitive projects - having been tested under seismic loading conditions in addition to static loads, this anchor supports use in regions and applications where seismic performance documentation is a project requirement.

Frequently Asked Questions

Can the Titen HD anchor be used in cracked concrete?

Yes. The Titen HD is specifically designed for optimum performance in both cracked and uncracked concrete, and has been tested under static and seismic loading conditions in both substrates.

Does installing the Titen HD require a special drill bit?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits, simplifying the installation process.

Can this anchor be removed and reinstalled?

No. The Titen HD screw anchor should be used one time only. Installing the anchor multiple times may result in excessive thread wear and reduce load capacity.

Is this anchor suitable for outdoor use?

The zinc-plated carbon steel Titen HD is recommended for permanent dry, interior non-corrosive environments. It can also be used for temporary exterior or outdoor applications, but is not intended for permanent outdoor or corrosive environments.
