The Simpson Titen HD 1/2 in. x 12 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor built for demanding structural applications in both cracked and uncracked concrete and masonry. Engineered and tested for performance under static and seismic loading conditions, this anchor's self-undercutting, non-expansion design makes it a reliable choice for structural connections where reduced edge distances and spacings are required. A specialized heat-treating process gives the tip the hardness needed for clean cutting while preserving the overall ductility of the anchor. Zinc-plated carbon steel construction makes it suitable for permanent dry interior environments and temporary outdoor use.

Key Features

• Qualified for static and seismic loading in cracked and uncracked concrete - gives structural professionals confidence that the anchor meets code requirements for a wide range of demanding applications.
• Self-undercutting thread design - efficiently transfers load to the base material without expansion, reducing stress on the surrounding concrete and enabling use at reduced edge distances and spacings.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, reducing tool costs and simplifying job-site setup.
• Hex-washer head design - eliminates the need for a separate washer and delivers a clean, finished appearance after installation.
• Specialized heat-treating process - creates tip hardness for reliable cutting performance without sacrificing the ductility of the carbon steel body.
• Zinc-plated finish - provides a layer of corrosion resistance suitable for temporary exterior applications where long-term outdoor exposure is not expected.
• Single-use anchor - installing the anchor multiple times may result in excessive thread wear and reduce load capacity, so it is designed and rated for one-time installation only.

Why This Product

• Dual-condition concrete performance - unlike anchors rated for uncracked concrete only, the Titen HD is specifically tested and qualified for both cracked and uncracked concrete under static and seismic conditions, making it a versatile anchor for structural and seismic-zone projects.
• Non-expansion mechanics for tighter layouts - the self-undercutting design places no outward expansion pressure on the base material, allowing installations at reduced edge distances and spacings where traditional expansion anchors would not be suitable.
• Straightforward installation with common tooling - compatibility with standard ANSI tolerance drill bits and a 3/4 in. hex drive means no specialty equipment is needed, keeping installation efficient and accessible on any job site.
• Engineered strength with a controlled heat-treat process - the purpose-built hardening treatment balances tip cutting ability with body ductility, so the anchor performs reliably in hard concrete and masonry without becoming brittle under load.

Frequently Asked Questions

Can the Titen HD anchor be used in cracked concrete?

Yes. The Titen HD heavy-duty screw anchor is specifically designed and tested for optimum performance in both cracked and uncracked concrete under static and seismic loading conditions.

Does installing the Titen HD require a special drill bit?

No special drill bit is required. The Titen HD anchor is designed to install using standard-sized ANSI tolerance drill bits, simplifying setup and reducing tool requirements on the job site.

Can the Titen HD anchor be removed and reinstalled?

No. The Titen HD screw anchor is intended for one-time use only. Installing the anchor multiple times may result in excessive thread wear, which can reduce its load capacity and compromise structural performance.

Is the Titen HD anchor suitable for outdoor use?

The zinc-plated carbon steel Titen HD anchor is recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications. It is not intended for permanent exposure to corrosive or wet exterior conditions.
