The Simpson Titen HD 1/2 in. x 6 in. Washer-Head Heavy-Duty Screw Anchor is a high-strength concrete screw anchor engineered for demanding structural applications in cracked and uncracked concrete, as well as masonry. The low-profile washer head makes it especially well-suited for sill plate anchoring, where modular wall and floor systems must sit flush on top without requiring notches cut into the wall framing to clear the anchor head. A T50 6-lobe drive eases installation and resists stripping, while serrated teeth on the tip reduce the torque needed to drive the anchor into concrete or masonry.

Key Features

• Qualified per ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete under static, wind, and seismic loading - gives contractors and engineers the code-compliant documentation needed for permitted structural installations.
• Standard fractional sizing - hole size matches anchor size - eliminates guesswork at the jobsite; drill a 1/2 in. hole with a standard ANSI tolerance bit and the anchor fits without upsizing or special tooling.
• No special drill bit required - compatible with standard ANSI tolerance drill bits already on hand, reducing tool costs and keeping installations straightforward.
• Washer-head design with a low installed profile - permits modular wall and floor systems to be placed directly over the anchor without notching framing members, saving time and preserving structural integrity.
• Removable after installation - ideal for temporary anchoring scenarios or applications where fixtures may need to be repositioned or removed at a later stage.
• Serrated tip teeth - facilitate cutting into concrete and masonry and reduce the torque required during driving, easing installation and reducing wear on the drive bit.
• T50 6-lobe drive - provides a positive, slip-resistant engagement that is less prone to cam-out or stripping compared to conventional drive styles, helping protect both the fastener and the driver bit.
• Includes a 1/2 in. socket adapter and two T-drive bits in each box - means the right installation accessories arrive with the anchors, so work can begin without a separate hardware run.
• Zinc plated carbon steel construction - delivers solid corrosion resistance for interior and protected applications; note that this finish is not recommended for permanent exterior use or highly corrosive environments.

Why This Product

• Code-ready for structural and seismic applications - ICC-ES AC193 and ACI 355.2 qualification for cracked and uncracked concrete means this anchor meets the documentation requirements that inspectors and engineers look for on permitted projects, removing a common approval hurdle.
• Purpose-built for sill plate and low-clearance installations - the washer head's minimal installed profile allows wall framing and modular floor systems to sit directly on top of the anchored sill plate, eliminating the labor and material cost of notching framing to clear a hex head.
• Installs with tools already in your kit - standard ANSI tolerance drill bits and the included socket adapter and T-drive bits handle the entire installation, so there is no need to source proprietary tooling or specialty bits before work begins.
• Removability adds long-term flexibility - unlike adhesive or expansion anchors that are permanent once set, the Titen HD screw anchor can be removed, making it a practical choice for temporary anchoring needs or installations where equipment layouts may change over time.

Frequently Asked Questions

Is the Simpson THD50600WH approved for use in seismic and wind loading applications?

Yes. The Titen HD is qualified in accordance with ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete under static, wind, and seismic loading conditions, making it suitable for demanding structural and code-compliant installations.

Do I need a special drill bit to install the THD50600WH?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits. Because it features standard fractional sizing, the hole size matches the anchor size - simply use a standard 1/2 in. drill bit.

Can the THD50600WH be used outdoors or in corrosive environments?

The anchor is zinc plated and is not recommended for permanent exterior use or highly corrosive environments. For applications requiring exposure to moisture or corrosive conditions, a different coating or anchor type should be considered.

Why is the washer-head design preferred for sill plate and modular wall applications?

The washer-head design provides a low installed profile, which allows modular wall and floor systems to be installed directly on top of the anchor without the need to notch the wall framing to accommodate the anchor head. This makes it particularly well-suited for sill plate applications where a hex-head anchor would be incompatible.
