The Simpson Strong-Tie Titen HD 1/2 in. x 5 in. Mechanically Galvanized Washer-Head Heavy-Duty Screw Anchor (Model THD50500WHMG) is a high-strength screw anchor engineered for use in cracked and uncracked concrete, as well as masonry. The low-profile washer-head design is ideal where a minimal installed head profile is required, making it especially well-suited for sill plate applications where modular wall and floor systems must sit flush - eliminating the need to notch wall framing to accommodate the anchor. The anchor's T50 6-lobe drive eases installation and is less prone to stripping, while its mechanically galvanized carbon steel construction is code listed for exterior use.

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.
