The Simpson Strong-Tie Titen HD 5/8 in. x 6 in. Washer-Head Heavy-Duty Screw Anchor (Model THDB62600WH) 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 clearance is required, allowing modular wall and floor systems to be installed directly on top without notching the wall framing to accommodate the anchor. Its 6-lobe T60 drive eases installation and is less prone to stripping than traditional drive styles.

Frequently Asked Questions

What type of base material is the Simpson THDB62600WH rated for?

The Titen HD THDB62600WH is qualified for use in both cracked and uncracked concrete, as well as masonry, 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. The hole size matches the anchor size - 5/8 in. - making bit selection straightforward.

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

The washer-head design provides a minimal installed head profile, which is critical for applications such as sill plates where modular wall and floor systems need to be installed on top of the anchor without requiring notching of the wall framing. It is also used in applications where a hex head is incompatible.

Can this anchor be removed after installation, and is it suitable for outdoor use?

Yes, the Titen HD is removable, making it well suited for temporary anchoring or situations where fixtures may need to be repositioned. However, because it is zinc plated, it is not recommended for permanent exterior use or highly corrosive environments.
