The Simpson Titen HD 5/8 in. x 5 in. Type 304 Stainless-Steel Heavy-Duty Screw Anchor is a premium concrete and masonry fastener engineered to deliver fast, efficient installation alongside long-lasting corrosion resistance in wet, moist, or damp environments. Built from Type 304 stainless steel and featuring an innovative heat-treated carbon-steel cutting thread, this heavy-duty screw anchor combines the corrosion protection of 300 Series stainless steel with the undercutting performance needed to securely transfer loads into concrete and masonry base materials - making it a reliable, cost-effective solution for demanding structural applications.

Key Features

• Qualified for static and seismic loading conditions - gives installers and engineers confidence that this anchor meets the structural demands of both standard and seismically active projects.
• Thread design undercuts to efficiently transfer the load to the base material - means the anchor achieves a strong, dependable hold in concrete and masonry without requiring additional hardware or special preparation.
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits - reduces tool costs and simplifies job-site setup, so crews can get to work without sourcing specialty equipment.
• Hex-washer head requires no separate washer - streamlines installation and delivers a clean, professional finished appearance with fewer components to manage.
• Innovative carbon-steel cutting thread with limited carbon-steel content - effectively cuts concrete during installation while keeping expansion forces low, reducing stress on the surrounding base material.
• Installs with an impact wrench or by hand tool - provides installation flexibility across different job-site conditions and tool availability.
• Single-use design - ensures thread integrity and full load capacity are preserved; reinstalling the anchor can cause excessive thread wear and compromise performance.

Why This Product

• Stainless steel construction purpose-matched to the environment - Type 304 stainless steel provides meaningful corrosion resistance in wet, moist, or damp conditions at a more accessible price point than Type 316, making it a smart choice when extreme chemical or salt-water exposure is not a factor.
• Seismic qualification adds project versatility - because this screw anchor is qualified for both static and seismic loading, it can be specified with confidence across a wider range of structural and code-sensitive applications without sourcing a separate product.
• Simplified installation reduces labor time - compatibility with standard ANSI tolerance drill bits and the built-in hex-washer head eliminates the need for specialty tools or extra components, helping crews complete concrete and masonry anchoring tasks faster.
• Engineered thread geometry for reliable load transfer - the undercutting thread design works directly with the base material to achieve a secure mechanical connection, giving contractors and specifiers confidence in the anchor's holding performance from the moment it is set.

Frequently Asked Questions

Can the Titen HD screw anchor be removed and reinstalled?

No. Use a Titen HD screw anchor one time only - installing the anchor multiple times may result in excessive thread wear and reduce load capacity.

Is a special drill bit required to install this anchor?

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

Is this anchor suitable for seismic applications?

Yes. The Titen HD is qualified for both static and seismic loading conditions, making it appropriate for use in seismically active regions.

What environments is the Type 304 stainless-steel version best suited for?

Type 304 is a cost-effective solution for less extreme applications where the environment may be wet, moist, or damp. For highly corrosive or extreme environments such as salt water or chemical exposure, Type 316 stainless steel is the recommended choice.
