The Simpson Titen HD 1/2 in. x 14 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor built for demanding structural connections in both cracked and uncracked concrete and masonry. Engineered and tested under static and seismic loading conditions, this self-undercutting, non-expansion anchor delivers reliable, high-capacity performance even at reduced edge distances and spacings - making it a dependable choice for critical structural applications. Its zinc-plated finish suits permanent dry interior environments as well as temporary outdoor use.

Key Features

• Qualified for static and seismic loading in cracked and uncracked concrete - gives you confidence that the anchor meets tested performance standards across a wide range of real-world and code-required conditions.
• Self-undercutting, non-expansion thread design - transfers load efficiently into the base material without exerting outward expansion pressure, allowing installation closer to edges and at tighter spacings than many traditional anchors.
• Specialized heat-treating process on the carbon steel tip - creates the hardness needed for clean cutting on installation while preserving the ductility of the anchor body, reducing the risk of brittleness under load.
• Installs with a standard 1/2 in. ANSI tolerance drill bit - no specialty tooling required, simplifying job site logistics and keeping your tool inventory lean.
• Integrated hex-washer head with 3/4 in. hex drive - eliminates the need for a separate washer, speeding up installation and delivering a clean, professional finished appearance.
• Zinc-plated carbon steel construction - provides a level of corrosion resistance suitable for temporary exterior exposure, broadening the range of environments where this anchor can be deployed.
• Single-use design - each anchor is intended for one installation only; reusing it risks excessive thread wear and reduced load capacity, so plan accordingly to protect connection integrity.

Why This Product

• Proven under seismic and static conditions - the Titen HD has been tested and shown to perform in both cracked and uncracked concrete under seismic loading, making it a practical choice for structures in earthquake-prone regions or projects with strict engineering requirements.
• No-expansion anchoring for tight layouts - because the self-undercutting thread design transfers load without expansion pressure, this heavy-duty screw anchor maintains strong holding power even at reduced edge distances and spacings, giving engineers and contractors greater layout flexibility.
• Streamlined installation process - compatibility with standard ANSI tolerance drill bits and an integrated hex-washer head means fewer components to source and faster setting on the job, reducing labor time on concrete and masonry anchoring tasks.
• Versatile environment rating - the zinc-plated finish extends usability from permanent dry interior structural connections to temporary outdoor applications, making this a single anchor solution across multiple project types without sourcing a separate product.

Frequently Asked Questions

Can the Titen HD screw anchor be used in cracked concrete?

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

Do I need a special drill bit to install the Titen HD anchor?

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

Can the Titen HD 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, which could compromise structural integrity.

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 exterior or highly corrosive environments in this finish.
