The Simpson Strong-Tie Titen HD 1/2 in. x 8 in. Mechanically Galvanized Washer-Head Heavy-Duty Screw Anchor (Model THD50800WHMG) is a high-strength screw anchor engineered for use in cracked and uncracked concrete, as well as masonry. The washer-head design delivers a minimal installed head profile, making it the ideal choice for sill plate applications where modular wall and floor systems must be installed directly on top of the anchor without notching the wall framing. The anchor's 6-lobe drive reduces driver bit slippage and makes installation faster and more reliable.

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.
