The Simpson Strong-Tie Titen Turbo 1/4 in. x 4 in. 316 Stainless-Steel Trim-Head Concrete and Masonry Screw is a precision-engineered concrete screw anchor built for demanding installations where corrosion resistance and reliable holding power are non-negotiable. Crafted from Type 316 stainless steel with a hardened, alloy-steel tip, this trim-head fastener is designed for use in severe environments including coastal, chemical-exposed, and other harsh outdoor conditions. Whether anchoring fixtures to concrete, brick, or masonry, this screw delivers superior tension load performance with a streamlined installation process that works with an impact driver or cordless drill.

Key Features

• Type 316 stainless-steel body for long-lasting corrosion resistance in severe environments - provides a higher level of defense against saltwater, chemicals, and harsh outdoor exposure compared to standard stainless-steel alloys, so the fastener retains its integrity over time.
• Hardened, alloy-steel tip with serrations to cut through concrete - the serrated cutting edge bites aggressively into concrete and masonry on contact, enabling immediate engagement and reducing the effort needed to start each fastener.
• Engineered TruShield coating provides additional protection against dissimilar metals - this added layer guards against galvanic corrosion when the screw contacts other metal components, extending the service life of the connection.
• Superior tension load performance - delivers reliable holding strength in structural and non-structural concrete and masonry applications, giving installers confidence in every fastened connection.
• 6-lobe drive's large contact area provides better bit grip for more secure driving, lower torque and longer bit life (T25 driver bit included) - the T25 6-lobe drive reduces cam-out and bit wear, meaning fewer stripped drives and more consistent results across an entire job.
• Matched-tolerance bit not required; use a standard ANSI drill bit for installation - no specialty tooling is needed to prep the hole, reducing setup time and simplifying the installation workflow.
• Designed for installation with an impact driver or cordless drill; installation using the Titen Turbo Installation Tool is recommended - compatible with common jobsite tools so installers can get to work without sourcing specialized equipment.
• Drill bit diameter: 3/16 in. - a clearly specified pilot hole size means faster prep and eliminates guesswork when selecting the correct drill bit.

Why This Product

• Type 316 stainless steel combined with the TruShield coating delivers a two-layer approach to corrosion defense - protecting the fastener both from environmental exposure and from galvanic reactions with dissimilar metals at the connection point.
• The trim-head profile and T25 6-lobe drive work together to provide a low-profile, secure installation with strong bit engagement, reducing the chance of cam-out or surface damage during driving.
• No matched-tolerance drill bit is required - a standard ANSI 3/16 in. drill bit is all that is needed to prep the hole, making this concrete screw a practical choice for both professionals and do-it-yourself installers.
• The hardened, serrated alloy-steel tip is specifically engineered to cut through concrete and masonry, so the screw engages the base material immediately and drives to full depth with less resistance.
