The Simpson Strong-Tie Titen Turbo 1/4" x 3-1/4" Trim-Head Screw Anchor delivers fast, reliable fastening in concrete and masonry applications. Engineered with a revolutionary thread design that reduces driving torque while maintaining superior holding power, this bronze-coated carbon steel anchor gives installers a trouble-free experience from first drive to final set. Whether you are anchoring wood to concrete or wood to masonry, the Titen Turbo's patented Torque Reduction Channel clears drilling dust from between the threads, virtually eliminating binding, stripping, and snapping during installation.

Key Features

• Trim Head profile - sits low and flush against the work surface for a clean, finished appearance in visible or trim applications
• T25 6-Lobe drive type - delivers excellent bit engagement and torque transfer, reducing cam-out and driver slippage during installation
• Torque Reduction Channel thread design - channels drilling dust away from the threads, significantly lowering driving torque and preventing binding, stripping, and snapping
• Zinc plated with ceramic coating in bronze - provides a durable, corrosion-resistant finish suited for both indoor and outdoor fastening environments
• Carbon steel construction - provides the structural strength needed for dependable holding power in concrete and masonry anchoring tasks
• 1/4" diameter x 3-1/4" length - sized for solid embedment depth in concrete or masonry, supporting strong wood-to-concrete and wood-to-masonry connections
• Requires 3/16" drill bit - a standard ANSI drill bit size, so no specialty tooling is needed to prepare your pilot hole
• T25 driver bit included - the correct bit is in the box and ready to use, eliminating the need for a separate trip to source tooling

Why This Product

• The Torque Reduction Channel between the threads actively removes drilling dust during driving, solving the common problem of torque buildup that causes anchors to bind or snap mid-installation - saving time and reducing fastener waste.
• The trim head profile makes this anchor an ideal choice for finish-sensitive work where a low-profile fastener is required, such as attaching wood trim or framing members directly against concrete or masonry surfaces.
• The zinc plated and ceramic-coated bronze finish adds a layer of corrosion resistance that a standard uncoated carbon steel screw anchor cannot match, making it a more durable option for applications exposed to moisture or varying conditions.
• The T25 6-lobe drive system pairs precisely with the included driver bit, giving installers consistent torque control and reducing the stripping issues common with Phillips or square-drive fasteners under heavy driving loads.

Frequently Asked Questions

What size pilot hole do I need to drill for this screw anchor?

This anchor requires a 3/16 in. diameter pilot hole, drilled using a standard ANSI drill bit. No specialty bit is required - a common 3/16 in. ANSI bit is all you need to prepare the hole before driving.

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

The Torque Reduction Channel is a feature built into the thread design of the Titen Turbo. It creates a path between the threads where drilling dust can collect and escape during installation. This significantly reduces torque buildup, which is the primary cause of binding, stripping, and snapping when driving screw anchors into concrete or masonry.

Is a driver bit included with this anchor?

Yes, a T25 driver bit is included in the packaging. This matches the T25 6-lobe drive type of the anchor and is ready to use right out of the box.

What is the coating on this anchor and what protection does it provide?

This anchor features a zinc plated finish with a ceramic coating in a bronze color. The combined zinc and ceramic coating provides corrosion resistance beyond standard zinc plating alone, helping the anchor maintain its integrity in demanding fastening environments.
