The Simpson Titen HD 1/2 in. x 4 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 with a proprietary heat treatment and an ASTM B695 Class 65 mechanically galvanized coating, this heavy-duty anchor is qualified for both interior and exterior anchoring applications - making it a dependable choice for demanding tasks such as sill plates, ledgers, post bases, holdown connections, and temporary bracing or formwork.

Key Features

• Head-stamped for easy identification - lets installers quickly confirm the correct anchor on the job site, reducing the risk of mix-ups during multi-fastener projects.
• Serrated teeth on the tip - facilitate cutting into the base material and reduce installation torque, making the anchor faster and less physically demanding 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 cleaner cutting without compromising the ductility of the anchor body, delivering a balance of toughness and performance.
• Hex washer head - eliminates the need for a separate washer in most applications, simplifying installation and reducing the number of components required on site.
• ASTM B695 Class 65 mechanically galvanized coating - qualifies the anchor for exterior exposure, protecting against corrosion where moisture and environmental elements are a concern.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits, so no additional tooling investment is needed.
• Removable after installation - supports temporary applications such as bracing and formwork, or situations where a fixture needs to be relocated without damaging the base material.

Why This Product

• Versatile base material approval - the Titen HD is rated for use in both cracked and uncracked concrete as well as uncracked masonry, giving contractors a single anchor solution that covers a wide range of structural anchoring scenarios.
• Interior and exterior qualified - the ASTM B695 Class 65 mechanically galvanized finish means this screw anchor is not limited to sheltered environments, making it a practical choice for exposed exterior connections like ledgers and sill plates without requiring an upgrade to a specialty product.
• Engineered for efficient installation - the combination of serrated tip geometry, a proprietary heat-treating process, and compatibility with standard ANSI tolerance drill bits keeps installation straightforward, reduces torque demands, and eliminates the need for specialty tooling or separate washers.
• Reusable in temporary applications - unlike many concrete fasteners that are permanent once set, the Titen HD can be removed and repositioned, making it a cost-effective choice for temporary bracing, formwork, and any application where fixture relocation is anticipated.
