The Simpson Titen HD 3/4 in. x 8-1/2 in. Mechanically Galvanized Heavy-Duty Screw Anchor is a high-strength carbon steel fastener engineered for demanding structural anchoring in cracked and uncracked concrete, as well as uncracked masonry. Built with a proprietary heat-treating process and an ASTM B695 Class 65 mechanically galvanized coating, this heavy-duty screw anchor is equally dependable in interior and exterior environments, making it a go-to solution for sill plates, ledgers, post bases, holdown connections, and temporary applications such as bracing and formwork.

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 during structural work.
• Serrated teeth on the tip facilitate cutting and reduce installation torque - makes driving the anchor into concrete or masonry faster and less physically demanding, speeding up the overall installation process.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes load capacity by engaging the concrete or masonry more effectively, supporting structural integrity over the long term.
• Specialized heat-treating process creates tip hardness for better cutting without compromising ductility - delivers a tip that cuts cleanly through hard base materials while the anchor body retains the flexibility needed to resist cracking under load.
• Hex washer head requires no separate washer unless required by code - simplifies installation and reduces the number of components to manage on site.
• ASTM B695 Class 65 mechanically galvanized coating qualifies this anchor for exterior applications - provides corrosion resistance that holds up in exposed outdoor conditions, giving confidence in long-term performance for both permanent and temporary installations.
• Installs using standard-sized ANSI tolerance drill bits with no special tooling required - cuts down on setup time and eliminates the need to source proprietary drill bits before starting work.

Why This Product

• Engineered for cracked concrete - unlike standard concrete fasteners, the Titen HD is specifically designed and qualified for use in both cracked and uncracked concrete, as well as uncracked masonry, giving structural professionals the confidence to anchor in real-world field conditions where concrete cracking is common.
• Removable and reusable for temporary applications - the screw anchor design allows for easy removal, making it a practical choice for temporary bracing, formwork, and situations where a fixture may need to be relocated without sacrificing holding strength during use.
• Dual-environment corrosion protection - the ASTM B695 Class 65 mechanically galvanized finish combined with the proprietary heat treatment means a single anchor model handles both interior and exterior applications, reducing the need to stock multiple product variants for different job conditions.
• Broad structural application range - from sill plates and ledgers to post bases and holdown connections, this heavy-duty concrete screw anchor covers a wide variety of load-bearing structural connections, making it a versatile fastener to keep on hand across residential and commercial construction projects.
