Simpson Strong-Tie Titen Turbo 1/4 in. x 2 1/4 in. 316 Stainless-Steel Trim-Head Concrete and Masonry Screw is a high-performance concrete screw anchor built for demanding environments where standard fasteners fall short. Constructed from Type 316 stainless steel and finished with an engineered TruShield coating, this trim-head masonry screw delivers long-lasting corrosion resistance in severe, chemical-exposed, or saltwater-adjacent conditions. Whether anchoring brackets to concrete, securing fixtures to masonry, or fastening hardware to brick, this 1/4 in. diameter screw anchor is engineered for reliable holding power and smooth, low-torque installation with an impact driver or cordless drill.

Key Features

• Type 316 stainless-steel body - provides long-lasting corrosion resistance in severe environments, making it a dependable choice for coastal, chemical-exposed, or outdoor installations where lesser materials degrade prematurely.
• Hardened, alloy-steel tip with serrations - cuts through concrete aggressively for immediate thread engagement, reducing the effort and time needed to start each fastener.
• Engineered TruShield coating - provides additional protection against dissimilar metals, helping prevent galvanic corrosion when the screw contacts other metallic components in the assembly.
• Superior tension load performance - means the anchor maintains its holding strength under demanding pull-out forces, giving installers confidence in structural and load-bearing applications.
• No matched-tolerance bit required - use a standard ANSI drill bit for installation, which simplifies job-site prep and eliminates the need to source proprietary tooling.
• Designed for installation with an impact driver or cordless drill - compatible with common job-site tools; installation using the Titen Turbo Installation Tool is recommended for best results.
• T25 6-lobe drive with large contact area - provides better bit grip for more secure driving, lower torque, and longer bit life, reducing frustration and bit wear over high-volume installations.
• 3/16 in. drill bit diameter required - a precise, defined pilot hole size ensures proper thread engagement and eliminates guesswork at the job site.
• 50 per package - a generous quantity per box supports larger projects and reduces the need for frequent reordering.

Why This Product

• Type 316 stainless steel combined with TruShield coating gives this masonry screw a dual layer of corrosion defense - the stainless body resists environmental degradation while the engineered coating guards against galvanic reaction with dissimilar metals, extending the service life of the entire connection.
• The T25 6-lobe drive delivers a large contact area between bit and fastener, translating to lower installation torque and reduced bit slippage - practical benefits that add up significantly across a package of 50 anchors.
• No proprietary drill bit is needed - compatibility with standard ANSI drill bits means this concrete screw fits into any existing workflow without additional equipment purchases.
• A hardened, serrated alloy-steel tip paired with a trim head profile makes this anchor well suited for applications where a lower-profile, clean finish is required alongside dependable concrete and masonry penetration.
