Simpson Titen 1/4 in. x 2-3/4 in. Hex-Head Stainless-Steel Concrete and Masonry Screw is an engineered anchoring solution from Simpson Strong-Tie built to fasten components securely to concrete, brick, grouted CMU, and hollow-block in environments where a medium level of corrosion resistance is required. Constructed from Type 410 stainless steel with a zinc-plated protective overcoat, this hex-head concrete screw threads directly into a pre-drilled pilot hole without requiring a separate expansion anchor, delivering reliable holding power in demanding structural and masonry applications.

Key Features

• Hex-head drive design - allows installation with standard hex drivers or wrenches, improving torque control and reducing cam-out on the job site
• Type 410 stainless steel construction with zinc-plated protective overcoat - provides a medium level of corrosion resistance for use in challenging environments where standard carbon-steel fasteners would be unsuitable
• Compatible with concrete, brick, grout-filled CMU, hollow-block, and some preservative-treated wood applications - gives contractors and specifiers versatility across a wide range of common base materials
• Direct-thread installation into a pre-drilled pilot hole - eliminates the need for a separate expansion anchor, streamlining the fastening process and saving installation time
• One appropriately sized 3/16 in. drill bit included in each box - ensures you have the correct bit on hand without a separate purchase, keeping work moving without interruption
• Trusted Simpson Strong-Tie engineering - designed to perform under the most demanding structural applications where specifiers and contractors require proven, dependable holding power

Why This Product

• Stainless steel where standard anchors fall short - the Type 410 stainless steel material paired with a zinc-plated protective overcoat makes this concrete screw a practical choice for masonry environments where moisture or mild corrosive conditions would degrade ordinary fasteners over time
• No expansion hardware required - this Titen screw anchors directly into the base material, reducing the total number of components needed on site and allowing for faster, cleaner installation in concrete, brick, and CMU applications
• Broad application coverage in a single fastener - suitability across concrete, brick, grout-filled CMU, hollow-block, and some preservative-treated wood means one screw handles a wide variety of structural anchoring tasks without switching between fastener types
• Everything needed for installation arrives in the box - the inclusion of a correctly sized drill bit means crews can begin work immediately, making this a convenient, job-ready solution backed by Simpson Strong-Tie engineering
