The Simpson Titen HD 1/2 in. x 6 in. Mechanically Galvanized Washer-Head Heavy-Duty Screw Anchor is a high-strength concrete and masonry anchor engineered for demanding structural connections in both cracked and uncracked concrete. Its low-profile washer head is purpose-built for sill plate applications where modular wall and floor systems must sit flush on top of the installed anchor, eliminating the need to notch wall framing to clear a taller hex head. The T50 6-lobe drive resists cam-out during installation, and the mechanically galvanized finish delivers code-listed corrosion resistance for exterior structural use.

Key Features

• Qualified per ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete - gives contractors and inspectors documented code compliance for static, wind, and seismic loading conditions without additional engineering justification.
• Standard fractional sizing with matching hole size - the 1/2 in. anchor installs into a 1/2 in. drilled hole, simplifying layout and eliminating guesswork on drill bit selection.
• Compatible with standard ANSI tolerance drill bits - no proprietary tooling required, reducing jobsite setup time and keeping installation accessible with commonly available equipment.
• T50 6-lobe drive - transfers torque more efficiently than a slotted or Phillips drive, reducing the likelihood of stripping and making it easier to achieve proper installation depth.
• Washer-head design with minimal installed profile - allows use in sill plate and modular framing applications where a hex head would require notching, keeping the assembly clean and code-compliant.
• Removable after installation - supports temporary anchoring scenarios or applications where fixtures may need to be repositioned, avoiding the permanent commitment of an epoxy anchor.
• Mechanically galvanized finish, code listed for exterior use - provides corrosion resistance suitable for outdoor structural connections without requiring a special-order coating upgrade.
• Includes a 1/2 in. socket adapter and two T-drive bits in each box - everything needed to begin driving anchors immediately arrives with the anchors, reducing the chance of missing accessories on the jobsite.

Why This Product

• One anchor, two concrete conditions - because this screw anchor is independently qualified for both cracked and uncracked concrete under seismic, wind, and static loads, it covers a broad range of structural applications without requiring separate products or additional engineering review.
• Washer head solves a real framing problem - the low installed profile eliminates the notching step that hex-head anchors require in sill plate and modular wall assemblies, saving labor and preserving the structural integrity of the framing members.
• Ready to install out of the box - the included socket adapter and two T-drive bits mean no separate accessory purchase is needed, and compatibility with standard ANSI drill bits keeps the tool requirement simple.
• Exterior-rated and removable - the mechanically galvanized finish is code listed for exterior applications, while the removable design adds flexibility for phased construction or temporary fixture placement that epoxy or expansion anchors cannot match.

Frequently Asked Questions

Can the THD50600WHMG be used in cracked concrete?

Yes. This anchor 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 THD50600WHMG is designed to install using standard-sized ANSI tolerance drill bits, and the hole size matches the 1/2 in. anchor size for straightforward installation.

Why choose the washer-head design over a hex-head anchor?

The washer head provides a low installed profile that is ideal for applications where a minimal head clearance is necessary - such as sill plate installations - allowing modular wall and floor systems to be installed directly on top without notching the wall framing to accommodate the anchor head.

Is this anchor removable after installation?

Yes. The Titen HD screw anchor is removable, making it well-suited for temporary anchoring scenarios or applications where fixtures may need to be repositioned or removed at a later time.
