The Simpson Titen HD 1/2 in. x 6 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for optimum performance in both cracked and uncracked concrete and masonry. Its self-undercutting, non-expansion design has been tested and shown to provide outstanding performance under both static and seismic loading conditions, making it a reliable choice for structural anchoring applications even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications, this zinc-plated anchor delivers the combination of strength, versatility, and straightforward installation that structural and masonry work demands.

Key Features

• Qualified for static and seismic loading in cracked and uncracked concrete - gives contractors and engineers confidence the anchor meets code requirements for a wide range of structural applications.
• Self-undercutting thread design - efficiently transfers load to the base material without expansion, reducing stress on the surrounding concrete and enabling use at reduced edge distances and spacings.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, keeping your existing toolkit fully compatible and eliminating extra equipment costs.
• Hex-washer head design - eliminates the need for a separate washer, simplifying installation and producing a clean, finished appearance on the completed fastening.
• Specialized heat-treating process on carbon steel - creates tip hardness for better cutting action while preserving ductility, so the anchor drives cleanly without becoming brittle.
• Zinc-plated finish - provides corrosion resistance suitable for temporary exterior or outdoor applications in addition to permanent dry, interior non-corrosive environments.
• Single-use anchor - installing the anchor multiple times may result in excessive thread wear and reduced load capacity, so each anchor is intended for one installation to maintain full structural integrity.

Why This Product

• Built for demanding structural anchoring - the Titen HD's self-undercutting, non-expansion characteristics make it suitable for structural concrete and masonry applications where performance in both cracked and uncracked base material is required, including seismic zones.
• Installation-friendly design - compatibility with standard ANSI tolerance drill bits and a hex-washer head that needs no separate washer means fewer steps, fewer accessories, and a faster installation process on the job site.
• Versatile application range - a single anchor design covers static and seismic loading conditions, reduced edge distance installations, concrete, and masonry, reducing the need to stock multiple anchor types for different project requirements.
• Trusted Simpson engineering - the heat-treating process that balances tip hardness with ductility reflects the precision manufacturing behind this anchor, ensuring consistent cutting performance and reliable load transfer across structural applications.

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.

Do I need a special drill bit to install the THD50600H?

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 this anchor be removed and reinstalled in the same hole?

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 THD50600H 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.
