Simpson THDB62100WH Titen HD 5/8 in. x 10 in. Washer-Head Heavy-Duty Screw Anchor by Simpson is a high-strength screw anchor engineered for demanding anchoring applications in cracked and uncracked concrete as well as masonry. The low-profile washer-head design makes this anchor ideal for sill plate applications and anywhere a minimal head profile is required, allowing modular wall and floor systems to be installed directly on top without notching the wall framing to accommodate the anchor head.

Frequently Asked Questions

Can the Simpson THDB62100WH be used in cracked concrete?

Yes. The Titen HD washer-head screw 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 THDB62100WH is designed to install using standard-sized ANSI tolerance drill bits. The hole size matches the anchor size, so a standard 5/8 in. drill bit is all that is needed.

Why is the washer head preferred over a hex head in certain applications?

The washer head provides a significantly lower installed profile than a hex head, making it ideal for sill plate applications where modular wall or floor systems need to be installed directly on top of the anchor without requiring notching of the wall framing. It is also used in applications where a hex-head design is physically incompatible.

Is this anchor suitable for permanent outdoor or corrosive environments?

No. The THDB62100WH features a zinc-plated finish and is not recommended for permanent exterior use or highly corrosive environments. For applications exposed to the elements or corrosive conditions, a stainless steel variant would be more appropriate.
