Simpson 1/4 x 1-3/4 Hex Titen Turbo Screw Anchor by Simpson is a high-performance concrete and masonry screw anchor engineered for fast, reliable wood-to-concrete and wood-to-masonry fastening. The patented reverse thread design cuts directly into concrete or masonry as you drive, delivering strong holding power with noticeably less torque than conventional anchors - so installations go faster and with less fatigue. The zinc-plated, ceramic-coated carbon steel construction provides lasting durability, and the recognizable standard blue color makes identification easy on the jobsite.

Key Features

• 1/4 in. diameter x 1-3/4 in. length - a compact screw anchor size well-suited for wood-to-concrete connections where a lower-profile fastener is needed without sacrificing holding strength
• Patented reverse thread design - cuts into concrete or masonry during driving, enabling smooth insertion with less torque so you can complete more anchors in less time with less effort
• 5/16 in. hex head drive type - works with standard hex-head drivers and a 5/16 in. wrench, so no specialty tooling is required and installation fits into a normal workflow
• Zinc-plated with ceramic coating - the dual-layer protective finish resists corrosion and extends the service life of the anchor in typical indoor and sheltered concrete anchoring applications
• Carbon steel material - provides the tensile and shear strength required for dependable structural connections in concrete and masonry substrates
• 3/16 in. drill bit diameter - requires only a 3/16 in. hole, meaning less material removal, faster hole prep, and a snug thread engagement for maximum holding power
• Standard blue color - allows quick visual identification and sorting on the jobsite, reducing the chance of mixing anchor sizes during installation

Why This Product

• The reverse thread cutting action means the anchor taps its own holding threads directly into concrete or masonry as it drives - eliminating the need for a separate tap step and speeding up the overall anchoring process
• The small 3/16 in. pilot hole requirement means less drilling time and less stress on the base material, making it a practical choice for concrete and masonry work where minimizing material disruption matters
• The 5/16 in. hex head configuration is compatible with widely available impact drivers and wrenches, so crews can install these anchors using tools already on hand without sourcing specialty bits
• The zinc-plated plus ceramic coating combination delivers an added layer of surface protection beyond basic zinc plating alone, giving the carbon steel anchor improved resistance to environmental exposure in typical anchoring conditions

Frequently Asked Questions

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

You need to drill a 3/16 in. diameter pilot hole in the concrete or masonry before driving this 1/4 in. Titen Turbo anchor. The anchor's reverse thread design then cuts its own holding threads into the base material as it is driven, so no separate tapping step is needed.

What drive tool or wrench is required to install this anchor?

This anchor uses a 5/16 in. hex head drive. You can install it with a standard 5/16 in. hex-head driver bit on an impact driver or drill, or with a 5/16 in. wrench - both of which are common tools that do not require any specialty accessories.

What is the coating on this anchor and why does it matter?

The anchor is zinc plated with an additional ceramic coating. This dual-layer finish provides corrosion resistance beyond standard zinc plating alone, helping extend the service life of the carbon steel anchor in typical concrete and masonry anchoring environments.

What applications is this screw anchor designed for?

The Simpson Titen Turbo is designed for wood-to-concrete and wood-to-masonry anchoring applications. The screw cuts directly into concrete or masonry, making it suitable for projects where a fast-driving, reliable concrete screw anchor is needed without extensive hole preparation.
