The Simpson Titen HD 3/8 in. x 5 in. Heavy-Duty Screw Anchor is a high-strength screw anchor engineered for optimum performance in both cracked and uncracked concrete and masonry. Built from carbon steel with a specialized heat-treating process and finished with a zinc plating, this anchor delivers outstanding structural reliability under static and seismic loading conditions alike. Its self-undercutting, non-expansion design makes it a trusted choice for demanding structural connections, even at reduced edge distances and spacings, and it is 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 confidence that the anchor meets performance requirements for both everyday structural loads and seismic events.
• Self-undercutting thread design - efficiently transfers load directly to the base material, maximizing holding strength without requiring an expansion mechanism that could stress surrounding concrete.
• Compatible with standard-sized ANSI tolerance drill bits - no specialty tooling is needed, which simplifies installation and reduces the cost and time associated with sourcing unique equipment.
• Hex-washer head included - eliminates the need for a separate washer, streamlining installation and delivering a clean, professional finished appearance.
• Specialized heat-treating process - creates tip hardness for clean, reliable cutting action while preserving the ductility of the carbon steel, balancing toughness with structural performance.
• Zinc-plated finish - provides corrosion resistance suitable for temporary exterior use, expanding the range of job site environments where the anchor can be confidently deployed.
• Single-use design - the anchor is intended for one installation only; reinstalling may cause excessive thread wear and reduce load capacity, so each anchor delivers its rated performance when installed correctly the first time.

Why This Product

• Dual-environment concrete performance - unlike anchors rated only for uncracked substrates, the Titen HD is specifically tested and approved for both cracked and uncracked concrete, giving structural professionals a single anchor solution that covers a wider range of real-world conditions.
• Seismic-rated for code-critical applications - tested and qualified under seismic loading conditions, this heavy-duty screw anchor is appropriate for structural connections in regions or projects where seismic performance is a code requirement.
• No-hassle installation with standard tooling - because the anchor works with standard ANSI tolerance drill bits and requires no separate washer, crews can install it quickly with the tools already on hand, keeping projects on schedule.
• Reduced edge distance capability - the non-expansion, self-undercutting design allows use at reduced edge distances and spacings, providing greater flexibility when anchor placement is constrained by structural geometry.

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, as well as uncracked masonry, under 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 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 its load capacity.

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 corrosive environment use.
