The Simpson Titen HD 3/8 in. x 6 in. Mechanically Galvanized Heavy-Duty Screw Anchor is a high-strength carbon steel anchor engineered by Simpson for reliable structural connections in cracked and uncracked concrete, as well as uncracked masonry. A proprietary heat-treating process combined with an ASTM B695 Class 65 mechanically galvanized coating delivers the corrosion resistance and cutting performance demanded by both interior and exterior anchoring applications - from sill plates and ledgers to post bases, holdown connections, temporary bracing, and formwork.

Key Features

• Head-stamped for easy identification - allows installers to confirm the correct anchor at a glance, reducing the risk of mix-ups on the job site.
• Serrated teeth on the tip facilitate cutting and reduce installation torque - the anchor seats faster and with less effort, lowering installer fatigue during high-volume applications.
• Thread design undercuts to efficiently transfer the load to the base material - maximizes holding strength in concrete and masonry so the connection performs as engineered.
• Specialized heat-treating process creates tip hardness for better cutting without compromising ductility - the anchor cuts cleanly through hard base materials while retaining the flexibility needed to resist structural loading.
• Hex washer head requires no separate washer unless required by code - fewer components to manage on site means faster installation and a cleaner finished connection.
• ASTM B695 Class 65 mechanically galvanized coating - provides corrosion resistance that qualifies the anchor for exterior applications, expanding its usability beyond interior-only fasteners.
• Designed to install using standard-sized ANSI tolerance drill bits - no proprietary tooling is needed, so contractors can get straight to work with equipment already on hand.
• Easy to remove after installation - makes the anchor a practical choice for temporary applications such as bracing and formwork, or any situation where a fixture may need 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 heavy-duty screw anchor covers a broader range of structural anchoring scenarios than products limited to a single substrate.
• Interior and exterior rated in one anchor - the ASTM B695 Class 65 mechanically galvanized finish means the same anchor can be specified confidently for exposed outdoor installations, eliminating the need to stock a separate exterior-grade fastener.
• Engineered for structural applications where holding power matters - the undercut thread design transfers load efficiently to the base material, making it appropriate for demanding connections such as sill plates, post bases, ledgers, and holdown assemblies.
• Removable design adds jobsite flexibility - because the Titen HD can be backed out and reused, it works equally well for permanent structural connections and temporary applications like formwork or bracing, giving contractors a single solution across multiple phases of a project.
