The Simpson Titen HD 3/8 in. x 2-1/2 in. Heavy-Duty Screw Anchor is a high-strength concrete and masonry screw anchor engineered for optimum performance in both cracked and uncracked concrete. Its self-undercutting, non-expansion design has been tested to deliver outstanding load transfer under both static and seismic loading conditions, making it a dependable solution for structural applications even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications, this zinc-plated carbon steel anchor combines ease of installation with the structural confidence required for demanding jobsite conditions.

Key Features

• Qualified for static and seismic loading conditions - gives contractors and engineers verified performance data for code-sensitive structural and seismic applications.
• Self-undercutting thread design - efficiently transfers load to the base material, maximizing holding strength in concrete and masonry without requiring an expansion mechanism.
• Compatible with standard-sized ANSI tolerance drill bits - no special drill bit required, so installation integrates into existing workflows without additional tooling costs.
• Hex-washer head design - eliminates the need for a separate washer, reducing hardware count and producing a clean, professional installed appearance.
• Specialized heat-treating process on carbon steel construction - creates tip hardness for cleaner cutting while preserving ductility, balancing installation performance with long-term structural integrity.
• Zinc-plated finish - provides corrosion resistance suitable for temporary exterior use, extending the range of approved application environments.
• Single-use anchor 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 plan placement carefully before driving.

Why This Product

• Dual-environment concrete performance - unlike anchors rated only for uncracked concrete, the Titen HD is specifically engineered and tested for both cracked and uncracked concrete under static and seismic conditions, reducing the need to source separate anchors for different structural scenarios.
• Structural versatility at tight tolerances - the non-expansion, self-undercutting design allows use at reduced edge distances and spacings, giving engineers and installers greater flexibility when working with constrained anchor layouts in concrete or masonry.
• Simplified installation without compromise - working with standard ANSI drill bits and a single hex-washer head that needs no added hardware, this heavy-duty screw anchor cuts installation time without sacrificing the load performance required for structural work.
• Heat-treated carbon steel for balanced toughness - the specialized tip-hardening process delivers the cutting capability needed to drive cleanly into concrete while maintaining the ductility that structural connection applications demand, all in a zinc-plated anchor rated for interior permanent use and temporary outdoor exposure.

Frequently Asked Questions

Can the Titen HD anchor be used in cracked concrete?

Yes. The Titen HD heavy-duty screw anchor is specifically designed for optimum performance in both cracked and uncracked concrete, and has been tested to provide outstanding performance under both static and seismic loading conditions in those environments.

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

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

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, compromising the integrity of the connection.

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. It may also be used for temporary outdoor applications, but is not intended for permanent exterior or corrosive environments.
