The Simpson Titen HD 5/8 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 deliver outstanding structural reliability under both static and seismic loading conditions, making it a dependable choice for demanding structural anchoring applications even at reduced edge distances and spacings. Zinc-plated for corrosion resistance, it is recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.

Key Features

• Qualified for static and seismic loading conditions - gives you confidence that the anchor meets the performance demands of both everyday structural loads and seismic events, supporting code-compliant installations.
• Self-undercutting thread design transfers load efficiently to the base material - the mechanical interlock with concrete or masonry maximizes holding strength without relying on expansion pressure, making it well-suited for reduced edge distances and close spacings.
• No special drill bit required; installs with standard-sized ANSI tolerance drill bits - simplifies job-site tooling and reduces setup time, so you can get to work with equipment you likely already own.
• Hex-washer head requires no separate washer - delivers a clean, finished appearance at the installed surface while eliminating the extra step and added cost of sourcing a matching washer.
• Specialized heat-treating process creates tip hardness for better cutting without compromising ductility - the anchor cuts cleanly into concrete or masonry on installation while retaining enough flexibility to resist sudden load events without brittle failure.
• Zinc-plated carbon steel construction - provides a level of corrosion resistance suitable for temporary exterior use, extending the anchor's practical range of application beyond strictly indoor environments.
• Single-use design preserves full load capacity - using the Titen HD screw anchor one time only ensures thread integrity is maintained; reinstalling a used anchor risks excessive thread wear and reduced holding performance.

Why This Product

• Engineered for the most demanding concrete anchoring scenarios - tested and proven in both cracked and uncracked concrete under static and seismic loading, this heavy-duty screw anchor is a reliable option when structural performance and safety margins cannot be compromised.
• Structural versatility at tight spacings - the non-expansion, self-undercutting mechanics allow use at reduced edge distances and spacings where traditional expansion anchors would be restricted, giving engineers and installers greater design flexibility.
• Fast, straightforward installation with common tooling - no proprietary drill bits, no special setting tools, and a hex-washer head that eliminates the need for a separate washer means fewer components to source and a quicker path from layout to finished anchor.
• Dual-environment suitability - zinc-plated carbon steel construction makes this screw anchor appropriate for permanent interior structural applications as well as temporary outdoor use, reducing the need to stock multiple anchor types for different site conditions.

Frequently Asked Questions

Can the Titen HD 5/8 in. x 6 in. 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 THDB62600H?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits, making installation straightforward with common tooling.

Can this anchor be used outdoors?

The zinc-plated carbon steel construction makes this anchor suitable for temporary exterior applications. It is recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications only.

Can the Titen HD screw 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.
