The Simpson Titen HD 5/8 in. x 6 in. Washer-Head Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for reliable fastening in cracked and uncracked concrete, as well as masonry. Its low-profile washer-head design is purpose-built for sill plate applications and similar installations where a minimal installed head clearance is critical - allowing modular wall and floor systems to sit flush on top without requiring notching of the wall framing. The T60 6-lobe drive reduces the likelihood of stripping during installation, and serrated teeth on the anchor tip cut into the base material while lowering the torque needed to drive it home.

Key Features

• Qualified per ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete - meets recognized engineering standards for static, wind, and seismic loading conditions, giving specifiers and installers confidence on code-sensitive projects.
• Standard fractional sizing - hole size matches anchor size - the 5/8 in. anchor installs into a 5/8 in. drilled hole, simplifying layout and eliminating guesswork on the jobsite.
• No special drill bit required - compatible with standard ANSI tolerance drill bits you likely already own, reducing tool costs and setup time.
• Removable after installation - ideal for temporary anchoring or any application where fixtures may need to be repositioned or removed later without damaging the substrate.
• Washer-head design with 1 3/4 in. head diameter - provides the broad bearing surface and low installed profile needed in applications where a hex head would interfere with overlying assemblies.
• Serrated tip facilitates cutting and reduces installation torque - makes driving into concrete or masonry easier and faster, reducing wear on tools and installer fatigue.
• 1/2 in. socket adapter and two T-drive bits included in each box - the necessary drive tooling comes with the anchors, so work can begin immediately without sourcing additional accessories.
• Zinc-plated carbon steel finish - provides corrosion resistance suitable for interior and protected applications; not recommended for permanent exterior or highly corrosive environments, helping buyers select the right product for the right setting.

Why This Product

• Built for low-clearance structural connections - the washer head's minimal installed profile makes this screw anchor the practical choice for sill plate anchoring and modular floor or wall system installations where a standard hex-head anchor would require time-consuming framing modifications.
• Code-compliant for demanding load conditions - qualification under ICC-ES AC193 and ACI 355.2 covers static, wind, and seismic loading in both cracked and uncracked concrete, meaning this anchor is ready for projects where engineered documentation and load ratings are required.
• Straightforward installation with no specialty tooling - standard ANSI drill bits, a matching 5/8 in. hole, and the included socket adapter and T-drive bits mean less time gathering materials and more time working.
• Flexibility to reposition or remove when plans change - unlike adhesive or expansion anchors that are difficult or impossible to reverse, the Titen HD screw anchor can be removed and reinstalled, making it a smart choice for phased construction or temporary fixture mounting in concrete and masonry.

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.
