The Simpson Titen HD 1/2 in. x 5 in. Mechanically Galvanized Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for reliable structural fastening in cracked and uncracked concrete, as well as uncracked masonry. Built around a proprietary heat treatment process and an ASTM B695 Class 65 mechanically galvanized coating, it performs dependably across a wide range of interior and exterior anchoring applications - from sill plates and ledgers to post bases, holdown connections, and temporary bracing or formwork where removability is essential.

Key Features

• Head-stamped for easy identification - allows installers to quickly confirm the correct anchor is in place without consulting packaging, reducing errors on the job site.
• Serrated teeth on the tip - facilitates cutting into the base material and reduces installation torque, making the anchor faster and less fatiguing to drive.
• Undercut thread design - efficiently transfers load to the base material, maximizing holding strength in both concrete and masonry substrates.
• Specialized heat-treating process - creates tip hardness for clean, consistent cutting while preserving ductility throughout the anchor body, so performance is not sacrificed for hardness.
• Hex washer head design - eliminates the need for a separate washer in most applications, saving time and reducing the number of components to manage on site.
• ASTM B695 Class 65 mechanically galvanized coating - qualifies this anchor for exterior use, providing enhanced corrosion resistance in exposed or moisture-prone environments.
• Removable by design - the screw anchor can be extracted and reinstalled, making it a practical choice for temporary applications such as bracing, formwork, or any fixture that may need to be relocated.
• Compatible with standard ANSI tolerance drill bits - no specialized tooling is required, so installation fits into existing workflows without added equipment costs.

Why This Product

• Versatile base material approval - rated for cracked and uncracked concrete as well as uncracked masonry, this anchor covers a broader range of structural anchoring scenarios than products approved for a single substrate, reducing the need to stock multiple anchor types.
• Interior and exterior rated - the ASTM B695 Class 65 mechanically galvanized finish means one anchor handles both protected indoor installations and demanding outdoor or exposed conditions without substitution.
• Engineered for efficiency - the combination of serrated cutting teeth, an undercut thread profile, and compatibility with standard ANSI drill bits shortens installation time and keeps the process straightforward whether the application is permanent structural work or temporary bracing.
• Purpose-built for critical structural connections - approved for sill plates, ledgers, post bases, seating connections, and holdown applications, this anchor is designed specifically for the load-transfer demands of heavy-duty structural anchoring rather than general-purpose fastening.
