The Simpson Titen 1/4 in. x 2-1/4 in. Phillips Flat-Head Stainless Steel Concrete and Masonry Screw is a mechanical anchor engineered by Simpson Strong-Tie for reliable, direct fastening to concrete, brick, grouted and hollow CMU, and some preservative-treated wood applications. Built from Type 410 stainless steel with a zinc-plated protective overcoat, this flat-head concrete screw is designed for environments where a medium level of corrosion resistance is required - giving specifiers and contractors a trusted anchoring solution for demanding structural applications without the need for a separate anchor or insert.

Key Features

• Phillips flat-head drive style - sits flush against the surface after installation for a clean, low-profile finish that works well when attaching components to concrete and masonry walls or floors
• Type 410 stainless steel construction with zinc-plated protective overcoat - provides a medium level of corrosion resistance, making these screws a practical choice for interior and exterior applications in moderately demanding environments
• Compatible with concrete, brick, grout-filled CMU, hollow-block masonry, and some preservative-treated wood - versatile base material coverage means fewer anchor SKUs to manage across different job site conditions
• Requires a 3/16 in. drill bit for installation - the correctly sized bit is included in each box, so installers can get to work immediately without sourcing separate tooling
• Threads directly into a pre-drilled hole - no sleeve, nut, or separate anchor component required, simplifying installation and reducing labor time on the job
• Engineered by Simpson Strong-Tie - a brand trusted by contractors and specifiers for optimum performance under demanding structural fastening applications

Why This Product

• Ready to install out of the box - each pack includes one appropriately sized 3/16 in. drill bit alongside the concrete screws, eliminating extra trips to source compatible tooling and keeping the installation process straightforward
• Corrosion resistance built into the material - the Type 410 stainless steel body combined with a zinc-plated protective overcoat makes these masonry screws a smart upgrade over standard carbon-steel alternatives in environments where moisture or mild corrosive exposure is a concern
• Broad application range across common base materials - suitable for solid concrete, brick, grout-filled and hollow-block CMU, and some preservative-treated wood, so a single fastener choice can cover multiple anchoring scenarios on the same project
• Backed by Simpson Strong-Tie engineering - Simpson mechanical anchors are designed for optimum performance in demanding structural applications, giving specifiers and contractors confidence in load-bearing and component-attachment situations alike
