Simpson Strong-Tie Titen Turbo 1/4 in. x 2 1/4 in. 316 Stainless-Steel Hex-Head Concrete and Masonry Screw is a next-generation structural concrete screw anchor engineered for reliable fastening in corrosive, severe, and chemically exposed environments. Built from a Type 316 stainless-steel body and finished with an engineered TruShield coating, this hex-head concrete screw delivers superior tension load performance while resisting the breakdown that can compromise standard masonry fasteners over time. Whether anchoring fixtures to concrete, brick, or masonry in coastal construction, pool enclosures, outdoor decks, or wastewater treatment facilities, this Simpson Strong-Tie screw anchor is designed to hold firm where ordinary fasteners fail.

Key Features

• Type 316 stainless-steel body for long-lasting corrosion resistance in severe environments - premium marine-grade material means this concrete screw anchor holds up against saltwater, chemicals, and harsh outdoor exposure without sacrificing structural integrity.
• Hardened, alloy-steel tip with serrations to cut through concrete - the serrated cutting edge bites aggressively into masonry, concrete, and brick for immediate, reliable thread engagement from the very first drive.
• Engineered TruShield coating provides additional protection against dissimilar metals - this specialized coating adds a critical barrier that guards against galvanic corrosion when the screw contacts other metal components, extending service life in demanding installations.
• Superior tension load performance - engineered to deliver strong holding power in concrete and masonry substrates, giving installers confidence that anchored connections will remain secure under load.
• Matched-tolerance bit not required; use a standard ANSI drill bit for installation - eliminates the need for proprietary tooling, saving time and reducing job-site complexity so you can get to work with the bits you already own.
• Designed for installation with an impact driver or cordless drill; installation using the Titen Turbo Installation Tool is recommended - compatibility with common power tools makes this concrete screw anchor practical and accessible for both professional tradespeople and experienced DIYers.
• Drill bit diameter: 3/16 in. - the correct pilot hole size is clearly specified, taking the guesswork out of hole preparation and helping ensure a precise, secure fit every time.
• Drive type: 5/16 in. hex head - the hex-head drive style provides a positive, no-slip interface with standard hex drivers, reducing cam-out and delivering more consistent installation torque.

Why This Product

• The Type 316 stainless-steel construction combined with the TruShield coating offers a two-layer approach to corrosion resistance - ideal for installers working in coastal, marine, chemical, or other severe exposure environments where a single layer of protection may not be enough.
• Because a matched-tolerance bit is not required, this masonry screw anchor installs with a standard ANSI drill bit, reducing the cost and hassle of sourcing specialty tooling for every job.
• The hardened, serrated alloy-steel tip is engineered specifically to cut through concrete and masonry, making this hex-head screw anchor a dependable choice for applications like ledger boards, conduit brackets, sill plates, and fixture mounting in tough substrates.
• Compatibility with both impact drivers and cordless drills means contractors and DIYers can use familiar equipment from their existing tool lineup, streamlining installation on a wide range of concrete and masonry fastening projects.
