The Simpson 5/8 in. x 6-1/2 in. Titen HD Mechanically Galvanized Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor built for demanding structural fastening in cracked and uncracked concrete, as well as uncracked masonry. Engineered by Simpson with a proprietary heat-treating process and an ASTM B695 Class 65 mechanically galvanized coating, this heavy-duty anchor is equally at home in interior and exterior environments. Whether you are anchoring sill plates, ledgers, post bases, holdowns, or temporary bracing and formwork, its precision thread design and serrated tip deliver reliable, efficient installation without the need for specialty tooling.

Key Features

• Head-stamped for easy identification - allows installers to quickly confirm the correct anchor is in use on the job site, reducing costly mix-ups on multi-anchor projects.
• Serrated teeth on the tip - facilitate cutting into concrete or masonry and reduce installation torque, making the anchor easier and faster to drive.
• Undercutting thread design - efficiently transfers load to the base material, helping the anchor achieve strong, dependable holding power in structural applications.
• Specialized heat-treating process - creates hardness at the tip for cleaner cutting without sacrificing ductility throughout the anchor body, balancing durability with toughness.
• Hex washer head - integrates the bearing surface directly into the head so no separate washer is needed in most applications, simplifying installation and reducing hardware count.
• ASTM B695 Class 65 mechanically galvanized coating - provides corrosion resistance that qualifies this anchor for exterior applications, extending service life in exposed or moisture-prone conditions.
• Removable and re-installable design - makes this screw anchor a practical choice for temporary applications such as bracing and formwork, or whenever a fixture needs to be relocated.

Why This Product

• Versatile base-material compatibility - rated for use in both cracked and uncracked concrete as well as uncracked masonry, this anchor covers a broader range of structural anchoring scenarios than fasteners limited to a single substrate type.
• Corrosion-resistant coating built to a recognized standard - the ASTM B695 Class 65 mechanically galvanized finish means you get a coating held to a defined performance benchmark, making this anchor a confident choice for exterior sill plates, ledgers, and holdown connections exposed to the elements.
• No special tooling required - the Titen HD installs with standard-sized ANSI tolerance drill bits, so crews can get to work immediately without sourcing proprietary bits or adapters, saving time and reducing job-site complexity.
• Engineered for both permanent and temporary structural work - the anchor's removability makes it equally useful for long-term structural connections and short-term applications like bracing or formwork, giving contractors a single reliable product across multiple phases of a project.
