Simpson 1/4 x 1-3/4 Flat Head Titen Turbo Screw Anchor by Simpson is a carbon steel concrete screw anchor engineered for fast, reliable wood-to-concrete and wood-to-masonry anchoring. The patented reverse thread design cuts cleanly into concrete and masonry surfaces, reducing the torque needed during installation while delivering superior holding power. Finished with a zinc plated and ceramic coating in standard blue, this flat head screw anchor resists corrosion and provides lasting performance in demanding structural fastening applications.

Key Features

• Flat Head profile - sits flush with the surface after installation for a clean, low-profile finish that won't snag or protrude in wood-to-concrete connections
• T30 6-Lobe drive type - reduces bit cam-out during driving, giving installers better torque control and a more secure fit compared to traditional hex or Phillips drives
• Zinc plated with ceramic coating - dual-layer protection helps resist corrosion and extends service life in concrete and masonry environments
• Carbon steel construction - delivers high strength and reliable holding power for structural anchoring tasks in concrete and masonry substrates
• Patented reverse thread design - cuts into concrete smoothly with less driving torque, speeding up installation and reducing installer fatigue
• 1/4 in. diameter x 1-3/4 in. length - compact sizing suited for applications with limited embedment depth or tighter clearance requirements
• 3/16 in. drill bit diameter required - precise pre-drill sizing ensures a tight, secure anchor fit in concrete or masonry, maximizing holding power

Why This Product

• The reverse thread design addresses one of the most common anchoring frustrations - excessive torque buildup - by allowing the screw to cut through concrete and masonry with noticeably less resistance, making it ideal for high-volume fastening tasks
• The T30 6-Lobe drive reduces cam-out risk compared to standard drive styles, meaning fewer stripped fasteners and more consistent installations in wood-to-concrete applications
• The zinc plated with ceramic coating provides a multi-layer corrosion barrier, making this anchor a dependable choice for concrete and masonry environments where moisture exposure is a concern
• The flat head design sits flush after installation, which is a practical advantage in finished surfaces or anywhere a protruding fastener head would interfere with adjoining materials

Frequently Asked Questions

What size hole do I need to drill before installing this anchor?

A 3/16 in. diameter pilot hole is required in the concrete or masonry substrate before driving this 1/4 in. screw anchor. Using the correct drill bit diameter is important for achieving the proper thread engagement and maximum holding power.

What drive tool is needed to install the Titen Turbo screw anchor?

This anchor uses a T30 6-Lobe drive, so a T30 Torx-compatible bit is required. The 6-lobe geometry provides a positive, cam-out resistant connection between the bit and the fastener during installation.

What applications is this screw anchor designed for?

The Titen Turbo flat head screw anchor is designed for wood-to-concrete and wood-to-masonry anchoring applications. The flat head profile allows the fastener to sit flush with the material surface, making it well suited for connections where a low-profile finish is required.

How does the reverse thread design benefit installation?

The patented reverse thread design enables the anchor to cut into concrete or masonry with less torque than conventional screw anchors. This smoother driving action reduces installer effort during high-volume anchoring work while still providing strong, reliable holding power once fully seated.
