The Simpson Titen Turbo 3/16 in. x 3-3/4 in. Hex-Head Concrete and Masonry Screw Anchor is a high-performance screw anchor engineered for fast, reliable fastening in concrete and masonry substrates. Its revolutionary Torque Reduction Channel thread design lowers driving torque while delivering superior holding power, making it a dependable choice for wood-to-concrete connections and structural anchoring applications. Like a traditional concrete screw anchor, the Titen Turbo drives directly into a pre-drilled hole in concrete or masonry - no separate expansion anchor required - but its advanced thread geometry takes installation ease and fastening consistency a step further.

Key Features

• Torque Reduction Channel (patent pending) - traps drilling dust between threads so it cannot obstruct thread action, significantly reducing the likelihood of binding, stripping, or snapping during installation
• Code listed per ICC-ES AC193 / IAPMO UES ER-712 - approved for concrete anchoring applications without cleaning dust from pre-drilled holes, saving time and eliminating an extra preparation step on the job
• Serrated screw point - makes it easier to start the fastener when securing wood to concrete, reducing effort and improving accuracy at the point of contact
• Compatible with standard ANSI drill bits - no matched-tolerance bit required, so installers can use tooling they already own without sourcing specialty accessories
• Zinc plated with a baked-on ceramic coating - provides a durable, corrosion-resistant finish suited for dry interior anchoring applications
• Designed for cordless drills and impact drivers - the 1/4 in. hex drive head works with standard hex-drive tool accessories, making installation straightforward with common jobsite tools

Why This Product

• Fewer installation headaches on every hole - the Torque Reduction Channel actively manages drilling dust inside the hole, addressing the root cause of the binding and snapping problems that make standard concrete screw anchors frustrating to use
• No hole-cleaning step required - code-listed approval for use without cleaning pre-drilled holes means faster installation sequences and fewer interruptions on the job, without sacrificing code compliance
• Works with tools and bits you already have - compatibility with standard ANSI drill bits and a 1/4 in. hex drive means no investment in specialty tooling, keeping this anchor practical and cost-effective for everyday concrete and masonry fastening
• Consistent, dependable holding power - the thread design that reduces driving torque also translates to reliable, repeatable fastening strength, giving installers confidence in every anchor placed in concrete or masonry

Frequently Asked Questions

Do I need to clean dust from the predrilled hole before installing the Titen Turbo?

No. The Titen Turbo is code listed in accordance with ICC-ES AC193 for concrete applications without cleaning dust from predrilled holes (IAPMO UES ER-712). The Torque Reduction Channel traps drilling dust where it cannot obstruct thread action, eliminating this extra preparation step.

What size drill bit do I need to install the TNT18334H?

A standard 5/32 in. ANSI drill bit is required. A matched-tolerance bit is not required; any standard ANSI drill bit of that diameter works for installation.

Can the Titen Turbo be installed with a standard cordless drill or impact driver?

Yes. The Titen Turbo is specifically designed for installation with a cordless drill or impact driver, and its 1/4 in. hex drive head is compatible with standard hex-drive tool accessories.

Is the TNT18334H suitable for outdoor or wet environments?

No. The TNT18334H Titen Turbo screw anchor is intended for use in dry interior environments only. It is zinc plated with a baked-on ceramic coating, but is not rated for exterior or high-moisture applications.
