Simpson Strong-Tie Titen Turbo 1/4 in. x 3 1/4 in. 316 Stainless-Steel Hex-Head Concrete and Masonry Screw is a heavy-duty fastener built specifically for corrosive, coastal, and chemically demanding environments. Crafted from Type 316 Stainless Steel and finished with an engineered TruShield coating, this concrete screw anchor delivers long-lasting holding power in applications where ordinary carbon-steel or lower-grade stainless fasteners fall short. Whether you are securing fixtures to concrete, attaching hardware to brick, or anchoring structural components in masonry, this screw anchor is engineered for reliable, professional-grade performance with straightforward installation.

Key Features

• Type 316 Stainless-Steel body - provides long-lasting corrosion resistance in severe environments, making this screw anchor a dependable choice for saltwater-exposed, chemical-rich, and outdoor applications where rust is a serious concern.
• Hardened, alloy-steel tip with serrations - cuts aggressively through concrete and masonry on contact, reducing the effort needed to engage the anchor and helping achieve a firm, consistent bite from the first thread.
• Engineered TruShield coating - provides additional protection against dissimilar metals, reducing galvanic corrosion risk when the fastener contacts other metal components in the assembly.
• Superior tension load performance - means installers can trust this screw anchor to maintain holding power under demanding structural and load-bearing conditions.
• No matched-tolerance bit required - a standard ANSI drill bit is all you need for installation, reducing tool costs and simplifying job-site prep without sacrificing performance.
• Compatible with an impact driver or cordless drill - allows flexible installation with common tools; installation using the Titen Turbo Installation Tool is recommended for best results.
• 3/16 in. drill bit diameter - gives installers a precise pilot-hole specification to follow, eliminating guesswork and helping ensure a secure, correctly sized anchor fit.
• 5/16 in. hex drive type - works with standard hex-drive sockets and bits, making this concrete screw compatible with the impact drivers and drills already on most job sites.

Why This Product

• Type 316 Stainless Steel - rather than lower-grade stainless alloys - delivers a meaningfully higher level of protection in environments exposed to saltwater, moisture, and harsh chemicals, extending the service life of the installation.
• The TruShield coating adds a targeted layer of defense against galvanic corrosion caused by dissimilar-metal contact, addressing a failure point that uncoated stainless fasteners can leave unprotected.
• Because no matched-tolerance drill bit is required, installers can use a standard ANSI bit already on hand, saving time and reducing the cost of specialized tooling on every project.
• Compatibility with both impact drivers and cordless drills means this masonry screw integrates naturally into existing workflows, with no need to invest in dedicated installation equipment for routine jobs.
