The Simpson Titen HD 1/4 in. x 2-3/4 in. Heavy-Duty Screw Anchor is a high-strength concrete and masonry screw anchor built for demanding structural applications where reliable load transfer is critical. Constructed from carbon steel with a zinc-plated finish, its self-undercutting, non-expansion thread design delivers outstanding performance in both cracked and uncracked concrete under static and seismic loading conditions - making it a trusted choice for structural anchoring even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.

Key Features

• Qualified for static and seismic loading conditions - gives engineers and installers confidence that the anchor meets rigorous performance requirements for a wide range of structural applications.
• Self-undercutting thread design - efficiently transfers load to the base material without expansion pressure, reducing the risk of edge blowout and allowing use at tighter spacings and edge distances.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits, saving time and eliminating the need for dedicated tooling on the job site.
• Hex-washer head - eliminates the need for a separate washer, simplifying installation and delivering a clean, finished appearance once the anchor is set.
• Specialized heat-treating process - creates tip hardness for better cutting during installation without compromising the ductility of the carbon steel body, balancing toughness with durability.
• Zinc-plated carbon steel construction - provides corrosion resistance suitable for temporary exterior use, extending the range of environments where the anchor can be deployed.
• Single-use design - the 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

• Engineered for both cracked and uncracked concrete - unlike anchors that are rated for only one substrate condition, the Titen HD has been tested and proven under both scenarios, giving buyers a single versatile solution for concrete and masonry anchoring projects.
• Seismic and static dual qualification - the anchor is tested under both static and seismic loading conditions, making it appropriate for structural work in seismically active regions without requiring a separate seismic-rated product.
• Straightforward installation with standard tooling - because no special drill bit is needed and the hex-washer head requires no additional hardware, installers can work faster and with less preparation, reducing overall installation cost and complexity.
• Structural-grade performance in tight spaces - the non-expansion, self-undercutting design allows the anchor to perform at reduced edge distances and spacings where conventional expansion anchors may not be appropriate, offering greater flexibility in structural layout.

Frequently Asked Questions

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

Yes. The Titen HD has been tested and shown to provide outstanding performance in both cracked and uncracked concrete under both static and seismic loading conditions.

Does this anchor require a special drill bit for installation?

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

Can this anchor be reused or reinstalled after initial installation?

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.

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 corrosive environment use.
