Simpson 1/4 x 1-1/4 Hex Titen Turbo Screw Anchor by Simpson is a high-performance concrete and masonry fastener engineered for fast, reliable wood-to-concrete and wood-to-masonry anchoring. Featuring a patented reverse thread design, this hex head screw anchor cuts directly into concrete or masonry without a sleeve or adhesive, delivering superior holding power with noticeably less driving torque. The zinc plated with ceramic coating provides corrosion resistance, while the carbon steel construction offers the strength needed for structural anchoring tasks. Whether you are securing sill plates, ledgers, or framing members to concrete slabs or block walls, this screw anchor streamlines installation and reduces labor time.

Key Features

• Hex Head with 5/16 in. Hex Drive - accepts a standard 5/16 in. hex socket or nut driver, so installation is fast and straightforward with common tools
• Patented reverse thread design - cuts cleanly into concrete or masonry for smooth driving with less torque, reducing installer fatigue and drill motor strain
• Zinc plated with ceramic coating - provides a dual layer of corrosion protection, extending service life in demanding environments
• Carbon steel construction - delivers the mechanical strength required for reliable wood-to-concrete and wood-to-masonry connections
• Standard Blue color designation - allows quick visual identification on the job site, helping keep anchor sizes organized
• 3/16 in. drill bit diameter required - a smaller pilot hole compared to the anchor diameter means less prep time and a tighter, more secure fit in the base material
• 1/4 in. diameter x 1-1/4 in. length - a compact form factor suited for thinner material connections and close-edge applications where space is limited

Why This Product

• The reverse thread design eliminates the need for sleeves, adhesives, or pre-expansion, making this anchor one of the most efficient options for securing wood members directly to concrete or masonry
• The 5/16 in. hex drive works with a standard wrench or impact driver socket, meaning no specialty tooling is required and installation speed is maximized on the job site
• The zinc plated with ceramic coating delivers dual-layer protection against corrosion, making this anchor a dependable choice in environments where moisture or concrete alkalis are a concern
• The 3/16 in. pilot hole requirement - smaller than the anchor body - creates a snug fit that contributes to the anchor's strong holding performance in both concrete and masonry base materials

Frequently Asked Questions

What drill bit size is needed to install this screw anchor?

A 3/16 in. diameter drill bit is required to create the pilot hole before driving this 1/4 in. Titen Turbo screw anchor into concrete or masonry.

What tool is used to drive the Titen Turbo screw anchor?

The anchor uses a 5/16 in. hex drive, so it can be installed with a 5/16 in. hex socket, nut driver, or compatible wrench - tools commonly found on most job sites.

What applications is this screw anchor designed for?

This screw anchor is designed for wood-to-concrete and wood-to-masonry anchoring applications. The reverse thread cuts directly into the base material, eliminating the need for sleeves or adhesives and making it well suited for securing framing members, sill plates, and similar connections.

What coating does this anchor have, and why does it matter?

This anchor features a zinc plated with ceramic coating - a dual-layer finish that helps resist corrosion. This added protection supports longer service life in conditions where moisture or concrete contact could otherwise degrade an uncoated fastener.
