Simpson Strong-Tie Titen Turbo 1/4" x 4" Flat-Head Screw Anchor is an engineered concrete and masonry fastener designed for wood-to-concrete and structural anchoring applications where reliable holding power and fast, clean installation are critical. Built from carbon steel with a zinc plated and ceramic coating finish, this flat-head screw anchor features a patented thread design that actively reduces driving torque - making it a go-to solution for contractors and builders who need consistent, trouble-free fastening in concrete or masonry substrates.

Key Features

• Torque Reduction Channel between threads - gives drilling dust a dedicated escape path, significantly reducing binding, stripping, and snapping during installation so you get a clean drive every time
• Revolutionary reverse thread design - lowers driving torque while cutting directly into concrete or masonry, meaning less physical effort and less wear on your driver
• T30 6-Lobe drive type - provides superior bit engagement over traditional hex or Phillips drives, reducing cam-out and keeping the fastener under control even at higher torque settings
• Flat-head profile - sits flush with the surface after installation, delivering a clean, low-profile finish suitable for finished framing and trim applications
• Zinc plated with ceramic coating - provides a dual-layer corrosion barrier that extends the service life of the anchor in demanding jobsite and structural environments
• 1/4" diameter with a 3/16" drill bit requirement - the slightly smaller pilot hole creates a tight, high-friction fit in the substrate, directly contributing to superior holding power without oversizing the hole
• 4" length - delivers meaningful embedment depth in concrete or masonry, supporting secure load transfer in wood-to-concrete connections
• Carbon steel construction - provides the strength and hardness needed for the self-tapping threads to cut cleanly through concrete and masonry without deforming

Why This Product

• The patented Torque Reduction Channel directly addresses the most common screw anchor failures - binding, stripping, and snapping - by channeling drilling dust away from the threads during driving, making difficult installations significantly more manageable
• The combination of a lower-torque thread design and T30 6-Lobe drive means faster installation with standard cordless drivers, reducing fatigue and increasing productivity on high-volume concrete anchoring jobs
• The zinc plated and ceramic coating delivers a dual-layer corrosion defense, making this anchor a dependable long-term fastener in structural applications where anchor integrity cannot be compromised
• The flat-head design sits flush at the surface, making this screw anchor the right choice when a clean, finished appearance matters alongside structural performance - such as in visible wood-to-concrete connections

Frequently Asked Questions

What size drill bit do I need to install the 1/4" x 4" Titen Turbo flat-head screw anchor?

A 3/16" drill bit is required for installation. The pilot hole is intentionally smaller than the 1/4" anchor diameter - this tight fit is what allows the threads to cut into the concrete or masonry and generate the anchor's superior holding power.

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

The Torque Reduction Channel is a revolutionary design feature built between the threads of the Titen Turbo. As the anchor drives into concrete or masonry, drilling dust accumulates and can cause torque-related problems like binding, stripping, and snapping. The channel gives that dust a place to go, keeping torque low and the installation clean and consistent.

What drive tool or bit does this flat-head screw anchor require?

This anchor uses a T30 6-Lobe drive - also commonly called a Torx T30. The 6-lobe design maximizes contact between the bit and fastener head, reducing the risk of cam-out and giving you better control during driving into hard substrates like concrete and masonry.

Is the zinc plated and ceramic coating suitable for structural anchoring applications?

Yes. The dual-layer finish - zinc plating combined with a ceramic coating - provides an enhanced corrosion barrier over standard zinc-only coatings. This makes the anchor well-suited for structural fastening applications where long-term durability and resistance to environmental exposure are important.
