The Simpson Titen HD 1/2 in. x 8 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. Backed by a proprietary heat treatment process and an ASTM B695 Class 65 mechanically galvanized coating, this anchor is built to perform across a wide range of demanding interior and exterior applications - from sill plates and ledger connections to post base installations, holdowns, and temporary work such as bracing and formwork.

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 multi-anchor projects.
• Serrated teeth on the tip facilitate cutting and reduce installation torque - less force required during driving means faster installs and reduced fatigue over the course of a project.
• Thread design undercuts to efficiently transfer the load to the base material - ensures a secure, high-strength connection that holds up under structural loading demands.
• Specialized heat-treating process creates tip hardness for better cutting without compromising ductility - the anchor cuts cleanly through concrete and masonry while retaining 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 needed on the job.
• ASTM B695 Class 65 mechanically galvanized coating - qualifies this anchor for exterior applications where corrosion resistance is critical, without sacrificing structural integrity.
• Designed for use with standard-sized ANSI tolerance drill bits - no specialty tooling is required, making setup straightforward and keeping installation costs down.

Why This Product

• Engineered for cracked concrete - unlike basic screw anchors, the Titen HD is specifically designed and qualified for use in both cracked and uncracked concrete, making it a dependable choice for structural applications where base material conditions may vary.
• Built-in corrosion protection for exterior use - the proprietary heat treatment paired with the ASTM B695 Class 65 mechanically galvanized finish means this anchor is fully rated for outdoor and exposed environments, eliminating the need to source a separate exterior-grade fastener.
• Removable for temporary or relocatable applications - because the Titen HD can be removed after installation, it is a practical solution for temporary bracing, formwork, or fixtures that may need to be repositioned, adding long-term flexibility to the job.
• Versatile across a broad range of structural connections - qualified for sill plates, ledgers, post bases, seating, and holdown applications, this single anchor covers multiple connection types, reducing the need to stock different fasteners for different tasks.
