The Simpson Strong-Tie Titen HD 5/8 in. x 8 in. Washer-Head Heavy-Duty Screw Anchor (Model THDB62800WH) is a high-strength carbon steel 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 where a minimal installed head profile is required, allowing modular wall and floor systems to be installed directly on top without notching the wall framing. A T60 6-lobe drive reduces stripping and eases installation, making this anchor a reliable choice for structural anchoring where code-qualified performance is essential.

Frequently Asked Questions

Can the Titen HD THDB62800WH be used in cracked concrete?

Yes. This anchor 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, and the hole size matches the 5/8 in. anchor size.

Why is a washer-head design used instead of a hex head?

The washer-head design provides a low installed profile, making it suitable for sill plate applications where modular wall and floor systems must be installed on top of the anchor without notching the wall framing. It also enables use in applications where a hex head is incompatible.

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. It is intended for interior or protected structural applications.
