The Simpson Titen HD 3/8 in. x 5 in. Mechanically Galvanized Heavy-Duty Screw Anchor is a high-strength carbon steel anchor engineered for reliable performance in cracked and uncracked concrete, as well as uncracked masonry. Its proprietary heat treatment and ASTM B695 Class 65 mechanically galvanized coating make it well suited for both interior and exterior anchoring applications, including sill plates, ledgers, post bases, holdown connections, and temporary work such as bracing and formwork. Designed to install with standard-sized ANSI tolerance drill bits, this heavy-duty screw anchor brings structural confidence to a wide range of residential and commercial concrete anchoring tasks.

Key Features

• Head-stamped for easy identification - allows installers to quickly confirm the correct anchor is in use on the jobsite, reducing costly mix-ups.
• Serrated teeth on the tip facilitate cutting and reduce installation torque - less force required during driving means faster installation and reduced fatigue over repetitive anchoring tasks.
• Thread design undercuts to efficiently transfer load to the base material - engineered load transfer means the anchor works with the concrete or masonry rather than against it, supporting stronger, more dependable connections.
• Specialized heat-treating process creates tip hardness for better cutting without compromising ductility - the anchor cuts cleanly through tough base materials while retaining the flexibility needed to resist real-world structural stresses.
• Hex washer head requires no separate washer (unless required by code) - the integrated washer head simplifies installation and reduces the number of components needed on the job.
• ASTM B695 Class 65 mechanically galvanized coating qualifies the anchor for exterior applications - corrosion resistance built into the finish means this anchor holds up in exposed outdoor conditions without requiring additional protective measures.
• Removable design supports temporary applications such as bracing and formwork - the ability to back the anchor out and reinstall elsewhere adds flexibility when working on projects where fixture locations may change.

Why This Product

• Verified performance in cracked concrete - many screw anchors are limited to uncracked base materials, but the Titen HD is specifically engineered and qualified for use in both cracked and uncracked concrete, making it a dependable choice for demanding structural conditions where base material integrity cannot always be guaranteed.
• No special tooling required - the anchor installs using standard-sized ANSI tolerance drill bits, so contractors and builders can work with the equipment already on hand rather than investing in proprietary installation tools.
• Dual-purpose suitability for permanent and temporary anchoring - the removable design makes this anchor equally practical for long-term structural connections like post bases and ledgers, and for temporary applications like formwork and bracing, delivering more value across a broader range of project types.
• Coating and heat treatment engineered to work together - the combination of a proprietary heat-treating process for tip hardness and an ASTM B695 Class 65 mechanically galvanized finish means this anchor is built for performance from the point of installation through years of service in interior and exterior environments.
