The Simpson Titen HD 3/4 in. x 10 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for demanding concrete and masonry fastening applications. Designed for optimum performance in both cracked and uncracked concrete, this anchor has been tested and shown to provide outstanding performance under static and seismic loading conditions, making it a trusted solution for structural connections even at reduced edge distances and spacings. Its self-undercutting, non-expansion design and specialized heat-treating process set it apart for applications where load reliability is non-negotiable. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.

Key Features

• Qualified for static and seismic loading conditions - gives contractors and engineers the confidence to specify this anchor for code-sensitive structural applications without additional testing or substitutions.
• Self-undercutting thread design efficiently transfers load to the base material - maximizes holding strength in concrete and masonry by mechanically engaging the substrate rather than relying on friction or expansion forces.
• No special drill bit required; installs with standard-sized ANSI tolerance drill bits - reduces tool costs and simplifies job-site setup, so crews can get to work without sourcing proprietary tooling.
• Hex-washer head requires no separate washer - streamlines installation and delivers a clean, professional finished appearance without additional hardware.
• Specialized heat-treating process creates tip hardness for better cutting without compromising ductility - the tip cuts cleanly into concrete while the anchor body retains the toughness needed to handle structural loads.
• Zinc-plated carbon steel finish is suitable for temporary exterior applications - provides a practical corrosion-resistance option for short-term outdoor use in non-corrosive conditions.
• Single-use design preserves full load capacity - the anchor is engineered for one-time installation; reuse risks excessive thread wear that could reduce holding strength, so each installation maintains its rated performance.

Why This Product

• Dual-environment performance in one anchor - because the Titen HD is qualified for both cracked and uncracked concrete under static and seismic conditions, it covers a wide range of structural fastening scenarios without requiring different anchors for different site conditions.
• Structural-grade reliability at tight layouts - the self-undercutting, non-expansion design is specifically suited for structural applications at reduced edge distances and spacings, giving engineers more layout flexibility without sacrificing load performance.
• Straightforward installation with standard tooling - compatibility with standard ANSI tolerance drill bits and a hex-washer head that eliminates a separate washer means fewer components, less prep time, and a cleaner result on the job site.
• Engineered material quality built for load transfer - the specialized heat-treating process balances tip hardness for clean cutting with overall ductility, delivering a concrete screw anchor built to perform in demanding structural connections rather than general-purpose light-duty fastening.

Frequently Asked Questions

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

Yes. The Titen HD anchor is specifically designed for optimum performance in both cracked and uncracked concrete. It has been tested and shown to provide outstanding performance under both static and seismic loading conditions in these environments.

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 without the need for specialized tooling.

Can this anchor be reused or reinstalled after removal?

No. The Titen HD screw anchor is intended for one-time use 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 anchor is recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications. It is not intended for permanent exterior or corrosive environment use.
