The Simpson Titen HD 3/4 in. x 7 in. Heavy-Duty Screw Anchor is a high-strength concrete and masonry screw anchor engineered for demanding structural connections in both cracked and uncracked concrete. Built from carbon steel with a specialized heat-treating process, this anchor delivers reliable performance under static and seismic loading conditions, making it a dependable choice for structural applications where precision and load transfer matter. Its self-undercutting, non-expansion design allows installation even at reduced edge distances and spacings, and its zinc-plated finish supports use in permanent dry, interior non-corrosive environments or temporary outdoor applications.

Key Features

• Qualified for static and seismic loading conditions - gives structural engineers and contractors confidence that this anchor meets performance requirements for both everyday and seismic-zone applications.
• Self-undercutting thread design efficiently transfers load to the base material - maximizes holding strength in concrete and masonry without relying on expansion force, reducing stress on the surrounding base material.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - saves time and eliminates the cost of proprietary tooling, simplifying the installation process on the job site.
• Hex-washer head requires no separate washer - streamlines installation and delivers a clean, finished appearance without additional hardware.
• Specialized heat-treating process creates tip hardness for better cutting without compromising ductility - allows the anchor to cut cleanly into concrete or masonry while maintaining the structural toughness needed for heavy-duty connections.
• Zinc-plated carbon steel construction - supports use in temporary exterior environments in addition to permanent dry interior applications, adding flexibility across job site conditions.
• Single-use design - installing the anchor one time only preserves full thread integrity and maintains rated load capacity, ensuring the connection performs as tested.

Why This Product

• Engineered for both cracked and uncracked concrete - unlike anchors limited to a single concrete condition, the Titen HD is tested and qualified for optimum performance across both, making it a versatile choice for a wider range of structural concrete connections.
• Ideal for seismic and high-load applications - the combination of self-undercutting thread geometry and non-expansion behavior makes this anchor well-suited for structural connections in seismic zones and other demanding loading environments where expansion-type anchors may not be appropriate.
• Installs with standard tooling - the 1 1/8 in. hex-washer head drives with common wrenching tools and accepts standard ANSI tolerance drill bits, reducing setup time and keeping installation costs down without sacrificing performance.
• Dual-environment suitability - the zinc-plated finish extends the anchor's usable range from permanent dry interior applications to temporary outdoor use, providing added flexibility when project conditions vary.

Frequently Asked Questions

Can the Titen HD screw anchor be used in both cracked and uncracked 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 in these environments.

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

No special drill bit is required. The Titen HD anchor is designed to install using standard-sized ANSI tolerance drill bits, making installation straightforward without the need for proprietary tooling.

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 load capacity, compromising the structural integrity of the connection.

Is this anchor suitable for outdoor or exterior 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.
