Simpson Strong-Tie Titen Turbo 3/16 x 3-1/4 Flat Head Screw Anchor is a high-performance concrete and masonry fastener engineered for fast, reliable installation in wood-to-concrete and structural anchoring applications. Featuring a patented thread design that dramatically reduces driving torque, this screw anchor makes concrete fastening quicker and less fatiguing while delivering the holding strength that demanding construction tasks require. The zinc plated with ceramic coating and carbon steel construction give this anchor lasting durability, while the T25 6-Lobe drive interface ensures precise, cam-out-resistant installation with a standard Torx bit.

Key Features

• Torque Reduction Channel between threads - gives drilling dust a dedicated escape path, significantly reducing binding, stripping, and snapping during installation so the anchor drives consistently without frustration
• Revolutionary thread design lowers driving torque - less force is needed to drive the anchor, reducing installer fatigue and the risk of overdriving or breaking the fastener in hard concrete or masonry
• Flat head profile - sits flush with the surface after installation for clean, low-profile fastening where protruding fastener heads would interfere with the finished assembly
• T25 6-Lobe drive type - the 6-lobe interface maximizes torque transfer to the fastener head, reducing cam-out and keeping the drive bit engaged even under high-torque driving conditions
• Zinc plated with ceramic coating - adds a layer of corrosion resistance beyond standard zinc plating, extending the working life of the anchor in environments where moisture or contaminants are present
• Carbon steel construction - provides the tensile strength and hardness needed to cut reliably into concrete and masonry while maintaining superior holding power once installed
• 3/16 in. diameter with 5/32 in. drill bit requirement - the tight fit between pilot hole and anchor diameter is engineered to produce the thread engagement that maximizes pullout and shear strength

Why This Product

• The patented Torque Reduction Channel addresses the most common failure points in concrete screw anchoring - binding, stripping, and snapping - making this anchor far more dependable for production work or repetitive fastening tasks in concrete and masonry.
• The flat head design combined with the flush-seating profile makes this screw anchor the right choice when surface clearance matters, such as attaching plates, fixtures, or framing members directly to concrete slabs or walls.
• The ceramic-enhanced zinc plating provides a more robust corrosion barrier than basic zinc alone, making this anchor appropriate for interior concrete applications where moisture exposure or chemical contact is a realistic concern.
• The 6-lobe T25 drive eliminates the frustration of slipping bits and damaged heads, keeping installation fast and controlled - an advantage on any project where a consistent, trouble-free fastening experience is critical.

Frequently Asked Questions

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

This anchor requires a 5/32 in. diameter drill bit to create the correct pilot hole in concrete or masonry. Using the correct bit size is essential - a hole that is too large will reduce thread engagement and compromise holding strength, while a hole that is too small will increase driving torque unnecessarily.

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

The Torque Reduction Channel is a patented design feature built into the thread profile of the Titen Turbo screw anchor. It provides a space for drilling dust and debris to escape as the anchor is driven into concrete or masonry. By clearing this material out of the thread path, the channel significantly lowers driving torque, which reduces the risk of binding, stripping, or snapping the anchor during installation and produces a more consistent, trouble-free fastening experience.

What drive tool or bit does this screw anchor use?

This anchor uses a T25 6-Lobe (Torx-style) drive interface. The 6-lobe geometry is designed to maximize torque transfer between the bit and the fastener head, which reduces cam-out and keeps the bit securely engaged during the high-torque demands of driving into concrete or masonry.

Is this anchor suitable for outdoor or moisture-exposed applications?

This anchor is zinc plated with an additional ceramic coating, which provides a corrosion-resistant barrier beyond standard zinc plating. While it offers improved moisture resistance compared to uncoated or basic zinc fasteners, always evaluate the specific environmental conditions of your project - including prolonged outdoor exposure or contact with treated lumber - to confirm this coating level meets your requirements.
