The Simpson Titen HD 3/8 in. x 5 in. Zinc-Plated Countersunk Head Heavy-Duty Screw Anchor is a carbon steel screw anchor engineered to set the standard for high-performance anchoring in cracked and uncracked concrete and masonry. Designed for dry, interior, noncorrosive environments or temporary outdoor applications, this anchor delivers reliable load performance under static, seismic, and wind-governed conditions - making it a dependable choice for structural and general fastening work where a clean, flush-mount profile is required.

Key Features

• Qualified for static and seismic loading conditions - gives you confidence that this anchor meets performance requirements for demanding structural and code-governed applications.
• Countersunk head style - allows for flush-mount installations that are not possible with a hex head, resulting in a cleaner surface appearance for exposed through-set applications.
• T50 6-lobe drive - reduces driver-bit cam-outs compared to traditional recessed anchor heads, making installation faster and less frustrating.
• No special drill bit required - designed to install using standard-sized ANSI tolerance drill bits at the same diameter as the anchor, eliminating the need to source additional tooling.
• Serrated teeth on the anchor tip - facilitate cutting into the base material and reduce installation torque, so the anchor drives in more smoothly and with less effort.
• Removable after installation - ideal for temporary anchoring or applications where fixtures may need to be relocated or adjusted over time, giving you greater flexibility on the job.
• Zinc-plated carbon steel construction - suited for dry, interior, noncorrosive environments or temporary outdoor use; a Type 316 stainless-steel version is available for applications requiring long-lasting corrosion resistance.
• Driver bit included in each box - means you have the correct bit on hand the moment you open the package, reducing downtime at the job site.

Why This Product

• Seismic and wind-load qualification built in - this heavy-duty screw anchor is qualified for both static and seismic loading conditions, so it works in applications where performance under dynamic forces is a genuine requirement, not just a marketing claim.
• A flush profile where it counts - the countersunk head design makes this anchor the right call whenever a hex head would protrude and interfere with a fixture, cover plate, or finished surface - a practical advantage that a standard screw anchor simply cannot offer.
• Straightforward installation with standard tooling - because the hole size matches the anchor size and no special drill bit is needed, installers can go straight to work with tools already on hand, and the included driver bit removes one more variable from the process.
• Removability adds long-term value - unlike adhesive or expansion anchors that are permanent once set, the Titen HD screw anchor can be removed, making it a smart choice for temporary structures, equipment mounts, or any situation where future adjustments are likely.
