Simpson Titen 1/4 in. x 3-1/4 in. Hex-Head Stainless Steel Concrete and Masonry Screw is a professional-grade mechanical anchor from Simpson Strong-Tie, engineered to install easily and securely into a variety of base materials including concrete, brick, grout-filled CMU, and hollow-block masonry. Made from Type 410 stainless steel with a zinc-plated protective overcoat, these concrete screws deliver a medium level of corrosion resistance suited for demanding environments - making them a trusted option for specifiers and contractors attaching components to concrete and masonry where moderate protection against corrosion is required.

Key Features

• Hex-head drive style - provides solid tool engagement for fast, reliable installation with a standard hex driver or nut driver
• Type 410 stainless steel construction with zinc-plated protective overcoat - delivers medium-level corrosion resistance for use in environments where standard carbon steel fasteners would be inadequate
• Compatible with concrete, brick, grout-filled CMU, and hollow-block masonry - gives contractors a single versatile fastener solution across a wide range of common base materials
• Suitable for select preservative-treated wood applications - expands usability beyond pure masonry anchoring to treated lumber connections
• Requires a 3/16 in. drill bit - one appropriately sized drill bit included in each box - eliminates a separate trip to source tooling and keeps installation moving without delay
• Threads directly into a pre-drilled hole - no separate expansion anchor needed, reducing parts count and speeding up the fastening process on the jobsite

Why This Product

• Stainless steel where it counts - Type 410 stainless steel construction paired with a zinc-plated overcoat addresses corrosion concerns in moderate-exposure environments where a standard zinc-coated screw anchor may fall short
• Trusted by specifiers and contractors for demanding structural applications - Simpson Strong-Tie mechanical anchors are specifically designed for optimum performance in challenging conditions, giving buyers confidence in load-critical fastening situations
• Broad base-material compatibility reduces the need for multiple anchor types - one screw works across concrete, brick, grout-filled and hollow CMU, and select preservative-treated wood, streamlining procurement and on-site inventory
• Drill bit included means the anchor is ready to install straight from the box - the correctly sized 3/16 in. drill bit ships with every box, eliminating guesswork and keeping installation efficient from the first hole
