The Simpson Titen HD 1/2 in. x 8 in. Washer-Head Heavy-Duty Screw Anchor (Model THD50800WH) by Simpson 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 for sill plate applications and anywhere a minimal installed head profile is required, allowing modular wall and floor systems to be installed directly on top without notching wall framing to accommodate the anchor. The 6-lobe T50 drive reduces the risk of stripping and eases installation, while serrated teeth on the anchor tip facilitate cutting and reduce installation torque.

Frequently Asked Questions

Can the Titen HD THD50800WH be used in cracked concrete?

Yes. This anchor is qualified in accordance with ICC-ES AC193 and ACI 355.2 for 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. Because it features standard fractional sizing, the hole size matches the anchor size - a 1/2 in. drill bit is used for this 1/2 in. anchor.

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

The washer-head design is ideal for applications where a minimal installed head profile is necessary. It allows modular wall and floor systems to be installed on top of the anchor without notching wall framing, and it accommodates screw anchor applications that are incompatible with a hex-head style.

Is this anchor suitable for permanent outdoor or corrosive environments?

No. This anchor is zinc plated and is not recommended for permanent exterior use or highly corrosive environments. For such conditions, a stainless steel or hot-dip galvanized anchor should be considered instead.
