The Simpson Strong-Tie Titen Turbo 1/4 in. x 3 1/4 in. 316 Stainless-Steel Trim-Head Concrete and Masonry Screw delivers professional-grade holding power for demanding fastening applications in corrosive and extreme environments. Built from Type 316 stainless steel and finished with an engineered TruShield coating, this concrete screw anchor is purpose-built for installations where standard fasteners fall short - think coastal construction, chemical-exposed settings, and any application where long-term corrosion resistance is non-negotiable. The trim head profile and T25 6-lobe drive make this an efficient, reliable choice for attaching fixtures, brackets, and structural elements directly to concrete, brick, or masonry substrates.

Key Features

• Type 316 stainless-steel body - provides long-lasting corrosion resistance in severe environments, making this anchor a dependable choice for saltwater exposure, chemical contact, and harsh outdoor conditions where lesser materials would degrade prematurely.
• Hardened, alloy-steel tip with serrations - cuts through concrete aggressively for immediate thread engagement, reducing the effort required to start each fastener and lowering the risk of slipping or skipping during installation.
• Engineered TruShield coating - provides additional protection against dissimilar metals, helping prevent galvanic corrosion when this anchor is used alongside other metal components or hardware.
• Superior tension load performance - means the anchor maintains its holding strength under demanding pull-out forces, giving installers confidence in structural and load-bearing connections.
• No matched-tolerance bit required - a standard ANSI drill bit works for installation, reducing the need for specialized tooling and keeping your kit simple on the job site.
• Designed for use with an impact driver or cordless drill - installation using the Titen Turbo Installation Tool is recommended, making this anchor compatible with common cordless tools already in most professionals' and DIYers' arsenals.
• T25 6-lobe drive with large contact area - provides better bit grip for more secure driving, lower torque, and longer bit life, reducing stripped drive recesses and slippage during installation; a T25 driver bit is included.
• Trim Head profile - sits low and clean against the substrate surface for a finished appearance where a flush, low-profile fastener head is preferred.
• 3/16 in. drill bit diameter required - a clearly specified pilot hole size removes guesswork and helps ensure correct installation depth and thread engagement every time.
• Quantity: 50 per package - provides enough fasteners for large projects without requiring multiple orders, adding convenience and value for production-level work.

Why This Product

• Marine-grade material where it matters most - Type 316 stainless steel is specified for its resistance to corrosion in severe environments, making this anchor well suited for coastal, poolside, chemical-exposed, and high-humidity applications where fastener longevity is critical.
• Extra protection against galvanic corrosion - the TruShield coating is engineered specifically to guard against dissimilar-metal reactions, an important consideration when fastening into concrete structures that also involve other metals or hardware.
• Versatile tool compatibility without special bits - because a standard ANSI drill bit handles the pilot hole and the included T25 driver bit handles the drive, this anchor integrates smoothly into existing workflows without requiring proprietary accessories.
• Reliable hold confirmed by superior tension load performance - for applications where anchors are subjected to pull-out forces, this performance rating provides measurable confidence compared to general-purpose masonry screws.
