Simpson Strong-Tie Titen Turbo 1/4 in. x 2 3/4 in. 316 Stainless-Steel Hex-Head Concrete and Masonry Screw is a next-generation structural fastener built for demanding installations in corrosive and severe environments. Crafted from Type 316 Stainless Steel with an engineered TruShield coating, this concrete screw anchor delivers long-lasting corrosion resistance and superior tension load performance when fastening into concrete, masonry, or brick. Whether you are securing fixtures in coastal construction, pool enclosures, outdoor decks, or chemical-exposed settings, this 1/4 in. diameter hex-head screw anchor from Simpson Strong-Tie is designed to drive smoothly, hold firmly, and resist the elements far longer than standard carbon-steel alternatives.

Key Features

• Type 316 stainless-steel body for long-lasting corrosion resistance in severe environments - marine-grade 316 stainless steel stands up to saltwater, coastal air, chemicals, and harsh outdoor weather, making this anchor a dependable choice where standard screws would corrode prematurely.
• Hardened, alloy-steel tip with serrations to cut through concrete - the serrated cutting edge bites aggressively into concrete and masonry on contact, providing immediate thread engagement and reducing the effort needed to start the screw.
• Engineered TruShield coating provides additional protection against dissimilar metals - this specialized coating acts as a buffer between the stainless-steel fastener and other metals in the assembly, helping prevent galvanic corrosion at the contact point and extending the life of the installation.
• Superior tension load performance - engineered for high-load applications, this screw anchor holds reliably under tension, giving installers confidence in structural and load-bearing connections.
• Matched-tolerance bit not required; use a standard ANSI drill bit for installation - unlike some specialty anchors that demand proprietary tooling, this screw works with a standard 3/16 in. ANSI drill bit, saving time and reducing the cost of installation.
• Designed for installation with an impact driver or cordless drill; installation using the Titen Turbo Installation Tool is recommended - compatibility with common cordless power tools means faster, more efficient installation on the job site or at home.
• 5/16 in. hex drive type - the hex-head drive style provides positive tool engagement, reducing the risk of cam-out and enabling consistent, controlled driving torque.

Why This Product

• Type 316 Stainless Steel construction delivers a higher level of corrosion resistance than standard stainless alternatives, making this anchor well-suited for coastal, marine, poolside, and chemical-exposed installations where fastener longevity is critical.
• The TruShield coating adds a layer of protection specifically against galvanic reaction with dissimilar metals, addressing a common failure point that standard concrete screws leave unprotected.
• No matched-tolerance drill bit is required - a standard ANSI 3/16 in. drill bit is all that is needed, reducing setup time and eliminating the need to source specialized tooling before starting the job.
• The hardened, serrated alloy-steel tip enables the screw to cut cleanly through concrete and masonry without pre-tapping, making installation straightforward for both experienced contractors and capable do-it-yourselfers.
