The Simpson Titen HD 1/2 in. x 5 in. Heavy-Duty Screw Anchor is a high-strength carbon steel screw anchor engineered for demanding concrete and masonry installations. Its self-undercutting, non-expansion design delivers outstanding performance in both cracked and uncracked concrete under static and seismic loading conditions, making it a dependable choice for structural applications even at reduced edge distances and spacings. A specialized heat-treating process hardens the tip for clean cutting while preserving ductility, and the zinc-plated finish supports use in permanent dry interior environments or temporary outdoor applications.

Key Features

• Qualified for static and seismic loading conditions - gives contractors and engineers confidence that the anchor meets rigorous performance standards for both everyday structural loads and seismic events.
• Self-undercutting thread design efficiently transfers load to the base material - the threads cut into concrete or masonry as the anchor is driven, creating a mechanical interlock that maximizes holding strength without an expansion sleeve.
• No special drill bit required - installs using standard-sized ANSI tolerance drill bits, so there is no need to invest in proprietary tooling or change out equipment mid-job.
• Hex-washer head requires no separate washer - the integrated washer head distributes clamping load evenly and delivers a clean, finished appearance once installed, saving a step during assembly.
• Specialized heat-treating process for tip hardness - the hardened tip cuts through concrete and masonry efficiently while the body retains ductility, reducing the risk of brittle failure under load.
• Zinc-plated carbon steel construction - provides corrosion resistance suitable for temporary exterior exposure, extending the range of job-site environments where the anchor can be used.
• Single-use design - the anchor is intended for one installation only; reinstalling may cause excessive thread wear and reduce load capacity, so each anchor delivers its rated performance when used as directed.

Why This Product

• Dual-environment certification - tested and approved for both cracked and uncracked concrete under static and seismic conditions, this heavy-duty screw anchor handles the widest range of structural anchoring scenarios without requiring a different product for each situation.
• Simplified installation with standard tooling - because standard ANSI tolerance drill bits are all that is needed, installation is straightforward and accessible for contractors who want reliable results without specialized equipment.
• Structural-grade performance at tight spacings - the non-expansion, self-undercutting mechanism allows the anchor to perform in structural applications even at reduced edge distances and spacings, giving designers more layout flexibility in congested areas.
• Integrated hex-washer head for a professional finish - the built-in washer eliminates a loose component, speeds up installation, and leaves a clean, consistent appearance across all anchor points on the finished structure.

Frequently Asked Questions

Can the Titen HD 1/2 in. x 5 in. 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 in these environments.

Do I need a special drill bit to install the THD50500H?

No special drill bit is required. The Titen HD anchor is designed to install using standard-sized ANSI tolerance drill bits, making it straightforward to install with commonly available tools.

Can the Titen HD anchor be removed and reinstalled?

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, which could compromise the integrity of the connection.

Is the THD50500H suitable for outdoor use?

The zinc-plated carbon steel Titen HD anchor can be used for temporary exterior applications. However, it is primarily recommended for permanent dry, interior non-corrosive environments. It is not intended for long-term permanent outdoor or corrosive environment use.
