The Simpson Titen HD 5/8 in. x 10 in. Heavy-Duty Screw Anchor is a high-strength screw anchor engineered for optimum performance in both cracked and uncracked concrete and masonry. Its self-undercutting, non-expansion design efficiently transfers load to the base material, making it well-suited for structural applications even at reduced edge distances and spacings. Tested under both static and seismic loading conditions, this zinc-plated carbon steel anchor is recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications where reliable holding strength is critical.

Key Features

• Qualified for static and seismic loading conditions - gives contractors and engineers confidence that the anchor meets the performance demands of code-sensitive and seismic-zone projects.
• Self-undercutting thread design - efficiently transfers the load to the base material without expansion pressure, reducing the risk of concrete splitting and allowing use at tighter edge distances and spacings.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits, so there is no need to purchase or stock specialty tooling before starting the job.
• Hex-washer head with no separate washer needed - simplifies installation and delivers a clean, professional finished appearance without additional hardware.
• Specialized heat-treating process on carbon steel construction - creates tip hardness for better cutting performance without compromising the ductility of the anchor, balancing installation ease with structural integrity.
• Zinc-plated finish - makes the anchor suitable for temporary exterior applications in addition to permanent dry, interior non-corrosive environments, adding flexibility across jobsite conditions.
• Single-use design - the anchor is intended for one-time installation only; reusing it may cause excessive thread wear and reduce load capacity, so this design ensures the connection maintains its rated integrity.

Why This Product

• Engineered for demanding structural applications - the non-expansion, self-undercutting mechanism allows installation closer to edges and at tighter anchor spacings than many traditional expansion anchors, giving designers greater layout flexibility without sacrificing holding strength.
• Dual-environment concrete performance - because the Titen HD is tested and qualified for both cracked and uncracked concrete under static and seismic loading, a single anchor product can cover a wider range of project conditions, reducing the need to stock multiple anchor types.
• Straightforward installation with standard tooling - compatibility with standard ANSI tolerance drill bits and an integrated hex-washer head means fewer components to manage on site and a faster, more predictable installation process for structural fastening crews.
• Trusted Simpson engineering with a specialized heat-treating process - the carbon steel body undergoes heat treatment to achieve tip hardness that cuts cleanly into concrete and masonry while preserving ductility, so the anchor performs reliably under the real-world stresses of structural loading.

Frequently Asked Questions

Can the Titen HD 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.

Do I need a special drill bit to install the Titen HD 5/8 in. x 10 in. anchor?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits, making installation straightforward without the need for specialty tooling.

Can the Titen HD screw 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, compromising the integrity of the connection.

Is the Titen HD suitable for outdoor use?

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