The Simpson 1/4 in. x 2-3/8 in. Countersunk Titen HD Heavy-Duty Screw Anchor in Type 316 Stainless Steel is a high-performance concrete and masonry anchor built for demanding structural and environmental conditions. The countersunk head profile delivers a flush-mount finish that keeps surfaces clean and unobstructed, making it a practical choice for exposed through-set applications. Type 316 stainless steel construction provides severe-level corrosion resistance for long-lasting reliability in harsh or moisture-prone settings, while the anchor's qualification for both static and seismic loading conditions makes it a dependable solution for a wide range of structural anchoring projects.

Key Features

• Qualified for static and seismic loading conditions - suitable for structurally demanding applications including those governed by seismic and wind requirements, reducing the need to source specialty anchors for code-sensitive work.
• Standard fractional sizing with hole size matching anchor size - the 1/4 in. drill hole matches the 1/4 in. anchor diameter exactly, simplifying layout and eliminating guesswork during installation.
• No special drill bit required - works with standard ANSI tolerance drill bits you already own, saving time and reducing tool costs on the job.
• T30 6-lobe drive - reduces driver-bit cam-outs during installation, resulting in faster, more controlled driving compared to traditional recessed anchor head styles.
• Serrated tip teeth - facilitate cutting into concrete or masonry and reduce installation torque, making the anchor easier to drive and lessening wear on tools.
• Countersunk head design - allows for flush-mount installations not achievable with a hex head, leaving a clean surface appearance for exposed applications.
• Removable anchor - can be extracted after installation, making it well suited for temporary anchoring or fixtures that may need to be repositioned or replaced.
• Type 316 stainless steel construction - delivers severe-level corrosion resistance for long-term performance in coastal, outdoor, or otherwise corrosive environments.
• Driver bit included in each box - provides everything needed to begin installation immediately without sourcing additional tooling separately.

Why This Product

• Built for corrosive and outdoor environments - Type 316 stainless steel goes beyond standard corrosion protection, making these anchors a reliable long-term fastening solution where moisture, salt air, or chemical exposure would degrade carbon steel alternatives.
• Engineered for structural confidence - qualification for both static and seismic loading conditions means this anchor meets the performance bar for code-sensitive concrete and masonry applications, not just everyday fastening tasks.
• Installation designed around the tools you already have - the same-size-as-anchor drill hole requirement and compatibility with standard ANSI drill bits mean no specialty tooling, no extra procurement, and no delays getting started.
• Flush finish without compromise - the countersunk head provides a low-profile, clean surface appearance that hex-head anchors cannot match, while the removable design adds flexibility for applications where fixtures may need to move or be adjusted over time.

Frequently Asked Questions

What type of corrosion resistance does this anchor provide?

This anchor is manufactured from Type 316 stainless steel, which provides severe-level corrosion resistance, making it well suited for long-lasting performance in demanding environments.

Can this anchor be used in seismic conditions?

Yes. The Titen HD is qualified for both static and seismic loading conditions, and offers industry-leading performance even in seismic and wind-governed conditions.

Do I need a special drill bit to install this anchor?

No special drill bit is required. The Titen HD is designed to install using standard-sized ANSI tolerance drill bits, and the hole size is the same as the anchor size - 1/4 in.

Why choose a countersunk head over a hex head style?

The countersunk head allows for flush-mount applications that are not possible with a hex head. It also leaves a cleaner surface appearance for exposed through-set applications where a low-profile finish is important.
