The Simpson 1/4 x 3-3/4 Flat Titen Turbo Screw Anchor is a high-performance concrete and masonry fastener engineered by Simpson for fast, reliable installation in wood-to-concrete and wood-to-masonry anchoring applications. Built from carbon steel with a zinc plated and ceramic coating finish, this screw anchor features a patented thread design that actively reduces driving torque - making it easier to install without sacrificing the holding power you need. Whether you're anchoring sill plates, furring strips, or structural framing members to concrete or masonry substrates, the Titen Turbo delivers consistent, trouble-free results from start to finish.

Key Features

• Innovative thread design with Torque Reduction Channel - gives drilling dust a designated escape path between threads, significantly reducing binding, stripping, and snapping during installation
• 1/4 in. diameter x 3-3/4 in. length - a versatile fastener size suited for a range of anchoring depths in concrete and masonry applications
• Flat head profile with T30 6-lobe drive - sits flush against the work surface for a clean finish, while the 6-lobe drive delivers superior bit engagement and reduced cam-out compared to standard drive types
• Zinc plated with ceramic coating - provides a durable, corrosion-resistant finish that extends the service life of the anchor in demanding job site conditions
• Requires 3/16 in. drill bit - a commonly available bit size that makes job site preparation straightforward and efficient
• Carbon steel construction - delivers the tensile strength and shear resistance required for dependable structural fastening in concrete and masonry
• Standard blue color coding - allows for quick visual identification on the job site, reducing the chance of mixing fastener sizes

Why This Product

• The Torque Reduction Channel built into the thread design directly addresses one of the most common frustrations with screw anchors - torque buildup that leads to bit slippage, stripped fasteners, and broken anchors - giving installers a smoother, more controlled drive every time
• The flat head profile allows the anchor to sit flush with the work surface, making it the right choice for applications where a low-profile fastener is required and surface interference cannot be tolerated
• The combination of zinc plating and ceramic coating means this anchor resists corrosion in environments where moisture or concrete alkalinity could degrade unprotected fasteners over time
• The T30 6-lobe drive type maximizes torque transfer from the bit to the fastener, reducing installer fatigue and improving accuracy - especially in high-volume or production anchoring scenarios

Frequently Asked Questions

What size drill bit is required for the 1/4 in. Titen Turbo screw anchor?

A 3/16 in. drill bit is required to pre-drill the pilot hole for this screw anchor. Using the correct bit size ensures proper thread engagement in the concrete or masonry substrate and helps achieve the full holding strength of the fastener.

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

The Titen Turbo features a revolutionary Torque Reduction Channel between the threads. This channel gives drilling dust a place to go during installation, which significantly reduces torque-related issues such as binding, stripping, and snapping - problems that are common with conventional concrete screw anchors.

What drive bit is needed to install the flat-head Titen Turbo?

This screw anchor uses a T30 6-lobe drive type. The 6-lobe geometry provides a more secure connection between the bit and fastener head compared to standard hex or Phillips drives, reducing cam-out and improving torque transfer during installation.

Is the Titen Turbo screw anchor suitable for outdoor or moisture-exposed applications?

This anchor features a zinc plated finish with an additional ceramic coating, which provides corrosion resistance for use in environments where moisture exposure is a concern. The dual-layer protective finish helps extend the service life of the fastener in demanding conditions.
