The Simpson Titen HD 3/4 in. x 5 in. Heavy-Duty Screw Anchor is a high-strength screw anchor engineered for structural concrete and masonry connections that demand reliable, long-term performance. Its self-undercutting, non-expansion design delivers outstanding results under both static and seismic loading conditions in cracked and uncracked concrete alike, making it a dependable choice for structural applications even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications, this anchor combines proven engineering with practical, job-site-friendly installation.

Key Features

• Qualified for static and seismic loading conditions - gives contractors and engineers confidence that the anchor meets demanding code requirements for both everyday structural loads and seismic events.
• Self-undercutting thread design - the threads undercut directly into the base material to efficiently transfer the load, eliminating reliance on expansion pressure and reducing the risk of edge blowout at tighter spacings.
• No special drill bit required - compatible with standard-sized ANSI tolerance drill bits, so installation fits into any existing workflow without extra tooling costs or delays.
• Integrated hex-washer head - no separate washer is needed, saving prep time and producing a clean, professional appearance once installed.
• Specialized heat-treating process on the carbon steel tip - creates the tip hardness needed for clean cutting into concrete and masonry without sacrificing the ductility of the anchor body, balancing toughness with structural flexibility.
• Zinc-plated carbon steel finish - provides a corrosion-resistant coating suitable for temporary exterior applications, extending the useful range of environments where the anchor can be deployed.
• Single-use design - the anchor is engineered for one-time installation; reinstalling after removal risks excessive thread wear and reduced load capacity, so each anchor delivers its full rated performance when used as intended.

Why This Product

• Versatile performance in cracked and uncracked concrete - tested and qualified for both substrate conditions under static and seismic loads, this heavy-duty screw anchor removes the guesswork from specification and suits a wide range of structural concrete and masonry applications.
• Structural capability at tighter layouts - the non-expansion, self-undercutting action makes it suitable for structural connections at reduced edge distances and spacings where traditional expansion anchors may not be appropriate, giving designers more flexibility on constrained projects.
• Simplified installation with standard tooling - because no specialized drill bit or separate washer is required, crews can install these concrete screw anchors quickly using equipment they already carry, reducing set-up time and keeping projects on schedule.
• Engineered material integrity - the specialized heat-treating process balances tip hardness for effective cutting with overall ductility, ensuring the anchor performs reliably in demanding masonry and concrete fastening applications without becoming brittle under load.

Frequently Asked Questions

Can the Titen HD anchor be used in cracked concrete?

Yes. The Titen HD anchor is specifically designed for optimum performance in both cracked and uncracked concrete, and has been tested to provide outstanding performance under both static and seismic loading conditions.

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

No special drill bit is required. The Titen HD screw anchor is designed to install using standard-sized ANSI tolerance drill bits, simplifying the installation process.

Can this anchor be reused or reinstalled after removal?

No. The Titen HD screw anchor should be used one time only. Installing the anchor multiple times may result in excessive thread wear and reduce its load capacity.

Is this anchor suitable for outdoor use?

The zinc-plated carbon steel Titen HD anchor is recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications. It is not intended for permanent exterior or corrosive environment use.
