The Simpson Titen HD 1/2 in. x 8 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. The low-profile washer-head design makes it the go-to choice for sill plate installations and modular wall or floor systems, where a standard hex-head anchor would require notching the framing - adding time and labor to the job. A T50 6-lobe drive reduces bit slippage and speeds up installation, while the mechanically galvanized finish delivers the corrosion resistance needed for exterior and code-listed applications.

Key Features

• Qualified to ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete - meets the testing requirements for static, wind, and seismic loading conditions, giving contractors confidence for structural and code-critical applications.
• Standard fractional sizing with matching hole and anchor diameter - no guesswork on drill bit selection; the 1/2 in. hole size matches the 1/2 in. anchor, simplifying layout and installation.
• No special drill bit required - installs with standard ANSI tolerance drill bits, reducing tool costs and keeping the job moving with equipment already on hand.
• Washer-head design with a low installed profile - allows modular wall and floor systems to sit flush on top of the anchor without notching the wall framing, saving time on sill plate and panel installations.
• Removable after installation - ideal for temporary anchoring or any application where fixtures may need to be repositioned or removed later.
• Mechanically galvanized finish, code listed for exterior use - provides corrosion protection suited for outdoor structural applications where exposure to the elements is a factor.
• T50 6-lobe drive - reduces cam-out and driver bit stripping compared to conventional drive styles, making installation faster and less prone to fastener damage.
• Includes a 1/2 in. socket adapter and two T-drive bits - everything needed to start driving anchors right out of the box, with no separate tool accessories to source.

Why This Product

• Built and certified for seismic and wind loading - qualification under ICC-ES AC193 and ACI 355.2 means this anchor is an appropriate choice for structurally engineered connections in seismic zones and high-wind regions, not just routine fastening tasks.
• The washer head solves a real installation problem - where a hex-head anchor is incompatible with the application or would require notching framing members, this low-profile design eliminates that extra step entirely, keeping sill plate and modular system installations clean and efficient.
• Corrosion protection that meets exterior code requirements - the mechanically galvanized coating is not just a finish upgrade; it is code listed for exterior applications, making this anchor a compliant choice for outdoor concrete and masonry connections without needing to source a separate product.
• Genuinely tool-ready right out of the package - with a socket adapter and two T-drive bits included, installers are not waiting on accessories; the anchor is ready to drive with a standard impact driver or drill, reducing setup time on the job site.

Frequently Asked Questions

Can this anchor be used in cracked concrete?

Yes. The Titen HD THD50800WHMG 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 Titen HD is designed to install using standard-sized ANSI tolerance drill bits. The standard fractional sizing means the hole size matches the anchor size, so a standard 1/2 in. drill bit is all that is needed.

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

The washer-head design provides a low installed profile that is essential in applications where a hex head is incompatible or where modular wall and floor systems will be installed directly on top of the anchor. This eliminates the need to notch wall framing to accommodate a taller anchor head.

Is this anchor removable after installation?

Yes. The Titen HD screw anchor is removable, making it ideal for temporary anchoring situations or applications where fixtures may need to be relocated or adjusted after initial installation.
