The Simpson Titen Turbo 3/16 in. x 3 1/4 in. Hex-Head Concrete and Masonry Screw Anchor is engineered by Simpson Strong-Tie for fast, reliable wood-to-concrete and wood-to-masonry fastening. At the core of its design is a patented Torque Reduction Channel that manages drilling dust between the threads, dramatically reducing the binding, stripping, and snapping that plague conventional concrete screw anchors. The result is a masonry screw that threads directly into a predrilled hole - no separate expansion anchor required - giving contractors and installers a consistently trouble-free fastening solution for dry interior concrete and masonry applications.

Key Features

• Torque Reduction Channel between the threads - traps drilling dust so it cannot obstruct thread engagement, reducing binding in the hole and lowering the risk of screws stripping or snapping mid-drive
• Code listed per ICC-ES AC193 for concrete without hole cleaning (IAPMO UES ER-712) - allows installation into predrilled holes without stopping to vacuum or blow out dust, saving measurable time on every anchor set
• Serrated screw point - bites into wood immediately on contact for easier, more controlled starts when fastening wood members to concrete or masonry
• Compatible with any standard ANSI drill bit (5/32 in. diameter) - no matched-tolerance specialty bit required, so installers can use common jobsite bits they already own
• Zinc plated with a baked-on ceramic coating - provides a durable finished surface that stands up to the demands of installation and protects the carbon steel fastener in service
• Designed for use with a cordless drill or impact driver - integrates into standard power-tool workflows without additional adapters, keeping installation fast and straightforward
• 1/4 in. hex drive head - mates directly with common hex chuck accessories and impact drivers for consistent torque transfer and reduced cam-out

Why This Product

• Faster installation without the frustration - the Torque Reduction Channel actively manages dust during driving, which means fewer stalled installs, fewer snapped anchors, and less time lost correcting mistakes on the jobsite
• Skip the hole-cleaning step legally - unlike many concrete fasteners that require vacuuming or blowing out predrilled holes, this screw anchor carries code listing under ICC-ES AC193 specifically permitting installation into uncleaned holes, a meaningful productivity advantage on high-volume projects
• Works with tools and bits you already have - no specialty matched-tolerance drill bit and no proprietary driver are needed; a standard ANSI 5/32 in. bit and a cordless drill or impact driver are all that is required, reducing setup cost and complexity
• Engineered and backed by Simpson Strong-Tie - this concrete screw anchor comes from a manufacturer with deep roots in structural fastening, and its performance claims are supported by third-party code listing (IAPMO UES ER-712), giving specifiers and installers documented confidence in the anchor's holding power

Frequently Asked Questions

What makes the Titen Turbo different from a standard concrete screw anchor?

The Titen Turbo features a patented Torque Reduction Channel between the threads that provides a path for drilling dust to escape. This significantly reduces torque-related issues such as binding, stripping, and snapping during installation, resulting in a smoother, more reliable fastening experience compared to conventional concrete screw anchors.

Do I need a special matched-tolerance drill bit to install the TNT18314H?

No. A matched-tolerance bit is not required. The Titen Turbo installs using a standard ANSI drill bit with a 5/32 in. diameter, making it compatible with common jobsite drill bits.

Can the TNT18314H be used without cleaning dust from the predrilled hole?

Yes. This screw anchor is code listed in accordance with ICC-ES AC193 for concrete applications without cleaning dust from predrilled holes (IAPMO UES ER-712), saving time and simplifying the installation process.

Is the TNT18314H suitable for outdoor or wet environments?

No. The Titen Turbo TNT18314H is designed for use in dry interior environments only. Its zinc-plated with baked-on ceramic coating provides corrosion resistance appropriate for interior applications but it is not rated for outdoor or wet conditions.
