The Simpson Titen HD 3/8 in. x 3 in. Mechanically Galvanized Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered by Simpson for reliable structural anchoring in cracked and uncracked concrete, as well as uncracked masonry. Its proprietary heat treatment process and ASTM B695 Class 65 mechanically galvanized coating make it a capable solution for demanding interior and exterior applications, including sill plates, ledgers, post bases, holdown assemblies, and temporary uses like bracing and formwork where removability is required.

Key Features

• Head-stamped for easy identification - allows installers to quickly confirm the correct anchor is in use, reducing errors on the job site.
• Serrated teeth on the tip facilitate cutting and reduce installation torque - faster, easier driving into concrete or masonry with less physical effort and tool strain.
• Thread design undercuts to efficiently transfer the load to the base material - optimizes load distribution for dependable structural performance in anchoring applications.
• 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 failure under load.
• Hex washer head requires no separate washer, unless required by code - simplifies installation by eliminating extra hardware in most applications.
• ASTM B695 Class 65 mechanically galvanized coating - provides corrosion resistance that qualifies the anchor for exterior applications as well as interior use.
• Approved for use in cracked and uncracked concrete, as well as uncracked masonry - broad base-material compatibility means fewer anchor SKUs needed across a project.
• Easy to remove after installation - supports temporary applications such as bracing and formwork, or situations where a fixture must be relocated.

Why This Product

• One anchor for a wide range of structural tasks - approval for cracked and uncracked concrete and uncracked masonry, combined with suitability for sill plates, ledgers, post bases, seating, and holdown applications, means this screw anchor covers a broad scope of residential and commercial anchoring work without requiring multiple product types.
• No special tooling needed - the Titen HD is designed to install using standard-sized ANSI tolerance drill bits, so crews can go straight to work without sourcing proprietary equipment or bits.
• Built-in corrosion protection for interior and exterior use - the proprietary heat treatment paired with the ASTM B695 Class 65 mechanically galvanized finish delivers the durability required for exterior exposure, making this anchor a practical choice for above-grade and outdoor anchoring conditions.
• Reusable in temporary applications - because the Titen HD screw anchor is designed to be removable, it is well suited for formwork, bracing, and other situations where anchors need to come out cleanly after the job is done, reducing waste and material cost.
