The Simpson Titen HD 5/8 in. x 8 in. Mechanically Galvanized Heavy-Duty Screw Anchor is a high-strength carbon steel fastener engineered for dependable structural anchoring 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 makes this heavy-duty screw anchor equally suited for interior and exterior applications, from sill plates and ledger connections to post bases, holdowns, and temporary work such as bracing and formwork. Designed for direct installation with standard ANSI tolerance drill bits, the Titen HD delivers load-transfer efficiency and long-term corrosion resistance where structural performance cannot be compromised.

Key Features

• Head-stamped for easy identification - allows installers to quickly confirm the correct anchor on the job site, reducing the risk of mix-ups during structural work.
• Serrated teeth on the tip - facilitates cutting into concrete and masonry while reducing installation torque, making driving faster and less fatiguing.
• Thread design that undercuts the base material - efficiently transfers load directly to the concrete or masonry, supporting reliable structural connections under demanding conditions.
• Specialized heat-treating process for tip hardness - enables clean, precise cutting through hard base materials without sacrificing the ductility needed for safe, code-compliant anchoring.
• 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 anchoring applications, providing corrosion resistance in exposed or moisture-prone environments.
• Removable after installation - makes this screw anchor practical for temporary applications such as bracing and formwork, or whenever a fixture needs to be relocated without replacing the anchor.

Why This Product

• Versatile base material approval - rated for use in both cracked and uncracked concrete, as well as uncracked masonry, this anchor covers a broader range of structural anchoring scenarios than fasteners limited to a single base material type.
• Corrosion-resistant coating built for real-world conditions - the ASTM B695 Class 65 mechanically galvanized finish provides meaningful protection against the elements, making this anchor a practical choice for exterior structural connections, not just controlled interior environments.
• Engineered tip and thread geometry that simplifies installation - the combination of serrated cutting teeth and an undercutting thread profile means faster driving, lower torque requirements, and efficient load transfer without requiring specialized tooling or drill bits.
• Dual-purpose utility for permanent and temporary applications - because the Titen HD can be removed and reused, it serves double duty on job sites where anchors may need to be repositioned, relocated, or used temporarily during the construction process.
