The Simpson Strong-Tie Titen HD 5/8 in. x 8 in. Mechanically Galvanized Washer-Head Heavy-Duty Screw Anchor (Model THDB62800WHMG) is a high-strength screw anchor engineered for reliable performance in cracked and uncracked concrete, as well as masonry. The low-profile washer-head design makes it the ideal choice for sill plate applications and installations where modular wall and floor systems must sit flush on top of the anchor - eliminating the need to notch wall framing. Its 6-lobe drive reduces the risk of stripping and makes driving easier, while the mechanically galvanized finish ensures it is code listed for exterior applications.

Frequently Asked Questions

What type of base material is the Titen HD THDB62800WHMG rated for?

The Titen HD is qualified for use in both cracked and uncracked concrete, as well as masonry. It is tested and listed in accordance with ICC-ES AC193 and ACI 355.2 for static, wind, and seismic loading conditions.

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

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits. Because it uses standard fractional sizing, the hole size matches the anchor size - in this case, a 5/8 in. drill bit.

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

The washer-head design provides a low installed profile, making it the preferred choice in applications where a hex head is incompatible or where minimal head clearance is required. This is especially useful in sill plate applications where modular wall or floor systems are installed on top, as no notching of wall framing is needed to accommodate the anchor.

Is the THDB62800WHMG suitable for outdoor or exterior use?

Yes. The mechanically galvanized coating on the Titen HD THDB62800WHMG is code listed for exterior applications, making it appropriate for outdoor installations where corrosion resistance is a consideration.
