The Simpson Titen HD 1/2 in. x 5 in. Mechanically Galvanized Washer-Head Heavy-Duty Screw Anchor is a high-strength concrete and masonry screw anchor engineered for demanding structural connections in both cracked and uncracked concrete. Its low-profile washer-head design is purpose-built for sill plate applications and anywhere a minimal installed head height is critical - modular wall and floor systems can be placed directly on top without notching the wall framing to clear the anchor head. The T50 6-lobe drive reduces cam-out during installation, and the mechanically galvanized carbon steel construction is code listed for exterior use, making this anchor a reliable choice for both interior structural work and exposed outdoor applications.

Key Features

• Qualified per ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete - engineered and code-approved for static, wind, and seismic loading conditions, giving you confidence in safety-critical connections.
• Standard fractional sizing - hole size matches anchor size - the 1/2 in. drill hole matches the 1/2 in. anchor diameter exactly, simplifying layout and eliminating guesswork on the jobsite.
• Compatible with standard ANSI tolerance drill bits - no proprietary tooling required, so you can install this anchor with equipment you already own.
• Includes a 1/2 in. socket adapter and two T-drive bits - everything needed to get started is in the box, reducing trips for additional hardware.
• Removable after installation - ideal for temporary anchoring or applications where fixtures may need to be repositioned or relocated later.
• Washer-head profile keeps the installed height minimal - enables use in applications where a hex-head anchor is incompatible, and allows floor and wall systems to sit flush without modification.
• Mechanically galvanized finish is code listed for exterior use - provides corrosion resistance suitable for outdoor and exposed installations where longevity matters.

Why This Product

• One anchor for cracked concrete, uncracked concrete, and masonry - the Titen HD's dual qualification under ICC-ES AC193 and ACI 355.2 means fewer SKUs to manage and a single solution across multiple substrate types and loading scenarios.
• Washer-head design eliminates framing modifications in sill plate work - the low installed profile lets modular wall and floor systems sit directly over the anchor, saving labor and material costs that would otherwise go toward notching.
• Exterior-rated and code listed right out of the box - the mechanically galvanized finish meets the requirements for outdoor use without requiring an upgrade to a specialty anchor, making it a practical choice for exposed structural applications.
• Straightforward installation with no special tooling - standard ANSI drill bits work with this anchor's fractional sizing, and the included socket adapter and T-drive bits mean the kit is ready to use without sourcing additional accessories.

Frequently Asked Questions

Can the Simpson THD50500WHMG be used in cracked concrete?

Yes. The Titen HD is qualified in accordance with ICC-ES AC193 and ACI 355.2 for use in both cracked and uncracked concrete under static, wind, and seismic loading conditions.

Do I need a special drill bit to install this anchor?

No special drill bit is required. The THD50500WHMG is designed to install using standard-sized ANSI tolerance drill bits, and the hole size matches the anchor size (1/2 in.) for straightforward installation.

Why would I choose a washer-head anchor over a hex-head anchor?

The washer-head design provides a low installed profile, making it ideal for applications where a minimal head height is necessary - such as sill plate installations where modular wall or floor systems are placed on top. This eliminates the need to notch wall framing to accommodate the anchor, which a hex-head design may require.

Is the THD50500WHMG suitable for exterior use?

Yes. The mechanically galvanized coating on the Titen HD is code listed for exterior applications, providing enhanced corrosion resistance for outdoor or exposed installation environments.
