Simpson Strong-Tie Titen Turbo 1/4 in. x 1 3/4 in. 316 Stainless-Steel Trim-Head Concrete and Masonry Screw is a high-performance concrete screw anchor built for demanding installations in severe and corrosive environments. Crafted from Type 316 stainless steel with a hardened, alloy-steel tip and a TruShield coating, this trim-head fastener is engineered to deliver reliable holding power when anchoring into concrete, masonry, or brick - giving contractors and serious DIYers a fastener that holds firm and lasts longer where standard alternatives fall short.

Key Features

• Type 316 stainless-steel body - provides long-lasting corrosion resistance in severe environments, making this anchor suitable for coastal, chemical-exposed, and other harsh conditions where inferior metals would degrade prematurely.
• Hardened, alloy-steel tip with serrations - the serrated cutting edge aggressively cuts through concrete and masonry on contact, enabling faster engagement and reducing the effort needed to start the fastener.
• Engineered TruShield coating - provides additional protection against dissimilar metals, reducing the risk of galvanic corrosion when the anchor contacts other materials.
• Superior tension load performance - means the anchor maintains a strong, reliable grip under pulling forces, giving you confidence that the connection will hold over time.
• T25 6-lobe drive with large contact area - provides better bit grip for more secure driving, lower torque, and longer bit life, reducing driver wear and minimizing the chance of cam-out during installation.
• No matched-tolerance bit required - use a standard ANSI drill bit for installation, saving you from sourcing specialty tooling and streamlining your workflow on the job site.
• Designed for installation with an impact driver or cordless drill - installation using the Titen Turbo Installation Tool is recommended, so the anchor works with tools you likely already own.
• 3/16 in. drill bit diameter - a precise, clearly specified pilot hole size means correct preparation is straightforward, helping you achieve consistent, code-ready results.
• T25 driver bit included - the correct drive bit ships with the anchor, so you can get to work immediately without a separate accessory purchase.
• Trim Head style - sits low and neat against the surface for a cleaner finished appearance in visible or finished-surface applications.

Why This Product

• Marine-grade stainless steel for severe-environment reliability - the Type 316 stainless-steel construction goes beyond standard corrosion resistance, making this screw anchor a dependable choice for applications exposed to saltwater, chemicals, or persistent moisture.
• TruShield coating adds a critical layer of protection - beyond the base stainless steel, the engineered coating guards against dissimilar-metal corrosion, meaning the anchor performs reliably even when in contact with other metals or treated lumber.
• Faster, lower-effort installation with tools you already own - because this concrete screw works with a standard ANSI drill bit and a cordless drill or impact driver, setup is simple and there is no need for specialty equipment or extra accessories beyond what is included.
• Better bit engagement reduces installation errors - the 6-lobe T25 drive geometry keeps the bit locked in securely during driving, lowering torque demands and reducing the risk of cam-out, stripped fasteners, or damaged pilot holes.
