Simpson Strong-Tie Titen Turbo 1/4 in. x 2-3/4 in. 6-Lobe Trim-Head Concrete and Masonry Screw Anchor, White is an engineered concrete and masonry screw anchor from Simpson Strong-Tie, designed for fast, reliable wood-to-concrete and wood-to-masonry fastening applications. The patent-pending Torque Reduction Channel lowers driving torque while delivering superior holding power, making installation consistently trouble-free with a cordless drill or impact driver.

Key Features

• Patent-pending Torque Reduction Channel that displaces dust where it can't obstruct the thread action, reducing the likelihood of binding in the hole
• Code listed in accordance with ICC-ES AC193 for uncracked concrete applications without cleaning dust from predrilled holes (IAPMO UES ER-712)
• Serrated screw point for easier starts when fastening wood
• Matched-tolerance bit not required; use a standard ANSI drill bit for installation
• Zinc plated with a baked-on ceramic coating
• Designed for installation with a cordless drill or impact driver; installation using the Titen Turbo Installation Tool is recommended
• Has a reduced head diameter to allow use with specific window manufacturers
• Drill bit diameter: 3/16 in.
• The 6-lobe drive's larger contact area provides better bit grip for more secure driving, lower torque and longer bit life (T25 driver bit included)

Frequently Asked Questions

What size drill bit is required to install the Titen Turbo TNTW25234TTR?

A standard ANSI drill bit with a 3/16 in. diameter is required. A matched-tolerance bit is not needed, so no specialized bit is required for installation.

What is the Torque Reduction Channel and why does it matter?

The patent-pending Torque Reduction Channel is a design feature built between the screw threads that displaces drilling dust away from the thread engagement zone. By giving dust a place to go, it significantly reduces torque-related issues such as binding, stripping, and snapping during installation.

Is the Titen Turbo approved for use without cleaning the predrilled hole?

Yes. The Titen Turbo is code listed in accordance with ICC-ES AC193 for uncracked concrete applications without cleaning dust from predrilled holes, as verified under IAPMO UES ER-712.

Why is a trim-head style recommended for certain window installations?

The trim-head version has a reduced head diameter compared to standard flat-head screw anchors, which allows it to be used in applications requiring compatibility with specific window manufacturers where a lower-profile fastener head is necessary.
