The Simpson Strong-Tie Titen Turbo 1/4 in. x 4 in. 316 Stainless-Steel Hex-Head Concrete and Masonry Screw is a professional-grade concrete screw anchor built to perform in corrosive and severe environments where standard fasteners fall short. Constructed from a Type 316 stainless-steel body and finished with an engineered TruShield coating, this hex-head masonry screw delivers long-lasting corrosion resistance for demanding applications including coastal construction, pool enclosures, wastewater facilities, and chemical-exposed concrete structures. The hardened, alloy-steel tip with serrations cuts aggressively through concrete, brick, and masonry, while the 5/16 in. hex drive design makes it compatible with a standard impact driver or cordless drill - no matched-tolerance drill bit required.

Key Features

• Type 316 stainless-steel body - provides long-lasting corrosion resistance in severe environments, making this anchor suitable for saltwater-exposed, chemical, and harsh outdoor applications where lower-grade stainless fasteners can fail prematurely.
• Hardened, alloy-steel tip with serrations - cuts through concrete and masonry aggressively on contact, resulting in faster, more reliable engagement with less effort during installation.
• Engineered TruShield coating - provides additional protection against dissimilar metals, reducing galvanic corrosion risk when the anchor is used in contact with other metal components.
• Superior tension load performance - means the anchor holds securely under demanding loads, giving installers confidence in structural and heavy-duty fastening applications.
• Standard ANSI drill bit compatible - a matched-tolerance bit is not required, so installers can use existing tooling and avoid the cost and inconvenience of sourcing specialty bits.
• Designed for impact driver or cordless drill installation - compatible with the tools most professionals and DIYers already own; installation using the Titen Turbo Installation Tool is recommended for optimal results.
• 3/16 in. drill bit diameter - the specified pilot hole size ensures a precise fit that supports the anchor's superior holding power in concrete and masonry.
• 5/16 in. hex head drive type - the hex head configuration provides a positive, slip-resistant drive connection that reduces cam-out and stripped drives during installation.

Why This Product

• The Type 316 stainless-steel construction combined with the TruShield coating delivers a two-layer defense against corrosion - offering durability in environments where both environmental exposure and contact with dissimilar metals are concerns.
• Because no matched-tolerance drill bit is required, installers can complete the job with a standard ANSI drill bit, reducing setup time and eliminating the need for specialty tooling on the job site.
• The hardened, serrated alloy-steel tip is engineered to cut into concrete and masonry rather than simply thread in, providing immediate engagement and contributing to the anchor's superior tension load performance.
• Compatibility with both an impact driver and a cordless drill gives this 1/4 in. concrete screw anchor broad versatility across job sites, whether working in tight spaces or open structural applications.
