The Simpson Titen HD Heavy-Duty Screw Anchor, 5/8 in. x 8 in. is a high-strength concrete and masonry screw anchor engineered for optimum performance in both cracked and uncracked concrete. Built from carbon steel with a specialized heat-treating process and a zinc-plated finish, this heavy-duty anchor delivers outstanding structural reliability under both static and seismic loading conditions - making it a dependable choice for demanding structural anchoring applications where edge distances and spacings may be reduced.

Key Features

• Qualified for static and seismic loading conditions - provides verified, tested performance across a wide range of structural and code-compliant applications, including seismic zones.
• Self-undercutting thread design - efficiently transfers load directly to the base material without expansion, reducing stress on the surrounding concrete and making it suitable even at reduced edge distances and spacings.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, simplifying the process and eliminating the need for additional tooling on the job site.
• Hex-washer head design - eliminates the need for a separate washer, speeding up installation and delivering a clean, professional finished appearance.
• Specialized heat-treating process - creates tip hardness for efficient cutting into concrete and masonry without sacrificing the ductility of the carbon steel body, balancing strength and toughness.
• Zinc-plated carbon steel construction - suitable for permanent dry, interior non-corrosive environments as well as temporary outdoor applications, offering flexibility across project types.
• Single-use design - the anchor is engineered for one installation only; reinstalling may cause excessive thread wear and reduce load capacity, ensuring the integrity of every anchored connection.

Why This Product

• Dual-condition concrete performance - unlike many screw anchors limited to uncracked concrete, the Titen HD is specifically designed and tested for use in both cracked and uncracked concrete, expanding its suitability across a broader range of real-world structural conditions.
• Seismic and static load qualification - tested and shown to perform under both static and seismic loading, this anchor is a reliable option for structural projects in areas with strict code requirements around earthquake resistance.
• Straightforward installation without specialty tooling - the compatibility with standard ANSI tolerance drill bits and the integrated hex-washer head means fewer components to manage and a faster, cleaner installation process.
• Engineered for structural confidence at tight spacings - the non-expansion, self-undercutting design makes this heavy-duty concrete screw anchor ideal for structural applications where reduced edge distances and anchor spacings are a practical necessity.

Frequently Asked Questions

Can the Titen HD anchor 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 and shown to provide outstanding performance under both 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 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.

Is the Titen HD anchor 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.
