The Simpson Titen Turbo 1/4 in. x 3-1/4 in. Hex-Head Concrete and Masonry Screw Anchor from Simpson Strong-Tie is engineered for fast, reliable fastening in concrete and masonry applications. At the heart of its performance is a revolutionary thread design that lowers driving torque while delivering superior holding power - making this one of the most installer-friendly concrete screw anchors available. The Torque Reduction Channel between the threads gives drilling dust a place to go, significantly reducing torque-related issues like binding, stripping, and snapping, so you get consistently trouble-free installation from start to finish. Whether you are anchoring wood to concrete or securing fixtures to block or brick, the Titen Turbo is built to perform.

Key Features

• Torque Reduction Channel between the threads - traps drilling dust so it cannot obstruct thread action, dramatically reducing the risk of binding, stripping, or snapping during installation for a cleaner, faster drive every time
• Code listed per ICC-ES AC193 for concrete without hole cleaning (IAPMO UES ER-712) - lets you skip the dust-cleaning step after drilling, saving time on every fastening job without sacrificing compliance or performance
• Serrated screw point - bites into wood immediately for easier starts when fastening wood to concrete, reducing the effort needed to initiate the drive
• No matched-tolerance bit required - installs with a standard ANSI drill bit, eliminating the need for specialty tooling and simplifying your setup
• Zinc plated with a baked-on ceramic coating - provides a durable protective finish that helps resist corrosion in appropriate interior environments
• Designed for use with a cordless drill or impact driver - compatible with common jobsite tools, making installation straightforward without dedicated specialty equipment
• 5/16 in. hex head drive type - provides positive engagement with standard hex-drive bits for reliable torque transfer and reduced cam-out

Why This Product

• Faster installs without the cleanup step - the Torque Reduction Channel manages drilling dust internally, and the code listing under ICC-ES AC193 means you are not required to clean the predrilled hole before driving, cutting down on labor time on every anchor point
• Engineered to reduce the most common installation failures - the thread design specifically targets binding, stripping, and snapping, the three most frustrating problems with concrete screw anchors, so you get predictable results rather than wasted fasteners and rework
• Works with tools and bits you already own - no proprietary matched-tolerance bit and no specialty driver required; a standard ANSI drill bit and a cordless drill or impact driver are all you need to get started
• Trusted Simpson Strong-Tie engineering in a concrete masonry screw - the Titen Turbo carries recognized code compliance credentials and delivers the holding power and installation consistency that professionals expect from Simpson Strong-Tie fastening products

Frequently Asked Questions

Do I need a special matched-tolerance drill bit to install the Titen Turbo TNT25314H?

No. A matched-tolerance bit is not required. You can install this screw anchor using a standard ANSI drill bit sized at 3/16 in. diameter, which simplifies setup and eliminates the need for specialty tooling.

Can I install the Titen Turbo without cleaning dust from the predrilled hole?

Yes. The TNT25314H 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 is specifically designed to trap drilling dust so it does not obstruct thread action during installation.

What tool should I use to drive the Titen Turbo screw anchor?

The Titen Turbo is designed for installation with a cordless drill or impact driver. The 5/16 in. hex head drive type is compatible with standard hex driver bits commonly used with these tools.

Is the Titen Turbo TNT25314H suitable for outdoor or wet environments?

No. This screw anchor is intended for use in dry interior environments only. The zinc plated with baked-on ceramic coating provides corrosion resistance appropriate for interior applications but is not rated for exterior, wet, or high-humidity conditions.
