The Simpson Titen HD 1/2 in. x 6 in. Washer-Head Heavy-Duty Screw Anchor (Model THD50600WH) by Simpson is a high-strength screw anchor engineered for use in cracked and uncracked concrete, as well as masonry. The washer-head design delivers a minimal installed head profile, making it the ideal choice for sill plate applications where modular wall and floor systems must sit flush on top of the anchor without requiring notching of the wall framing. The anchor's 6-lobe drive system eases installation and is less prone to stripping, delivering reliable performance in demanding structural applications.

Key Features

• Qualified in accordance with ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete for static, wind and seismic loading conditions
• Standard fractional sizes - the hole size matches the anchor size
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits
• Removable - ideal for temporary anchoring or applications where fixtures may need to be moved
• Washer head allows screw anchor applications incompatible with a hex head
• For added convenience, a 1/2-in. socket adapter and (2) T-drive bits are included in each box
• Serrated teeth on the tip of the Titen HD screw anchor facilitate cutting and reduce installation torque
• Zinc plated; not recommended for permanent exterior use or highly corrosive environments

Frequently Asked Questions

Is the Simpson THD50600WH approved for use in seismic and wind loading applications?

Yes. The Titen HD is qualified in accordance with ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete under static, wind, and seismic loading conditions, making it suitable for demanding structural and code-compliant installations.

Do I need a special drill bit to install the THD50600WH?

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 - simply use a standard 1/2 in. drill bit.

Can the THD50600WH be used outdoors or in corrosive environments?

The anchor is zinc plated and is not recommended for permanent exterior use or highly corrosive environments. For applications requiring exposure to moisture or corrosive conditions, a different coating or anchor type should be considered.

Why is the washer-head design preferred for sill plate and modular wall applications?

The washer-head design provides a low installed profile, which allows modular wall and floor systems to be installed directly on top of the anchor without the need to notch the wall framing to accommodate the anchor head. This makes it particularly well-suited for sill plate applications where a hex-head anchor would be incompatible.
