The Simpson Titen HD 1/4 in. x 2-3/8 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor is a state-of-the-art concrete and masonry anchoring solution engineered for demanding environments where corrosion resistance cannot be compromised. Built from Type 316 stainless steel and fitted with innovative heat-treated carbon-steel cutting threads, this heavy-duty screw anchor delivers fast, efficient installation alongside long-lasting durability - making it the go-to choice for salt water exposure, chemical environments, and any application where both static and seismic load qualifications are required.

Key Features

• Qualified for static and seismic loading conditions - gives you confidence the anchor meets structural requirements for a wide range of code-sensitive concrete and masonry projects.
• Undercutting thread design efficiently transfers load to the base material - maximizes holding strength in concrete and masonry so you can trust the connection under real-world stress.
• No special drill bit required; installs using standard-sized ANSI tolerance drill bits - reduces tool costs and simplifies job-site prep since no proprietary equipment is needed.
• Hex-washer head requires no separate washer - speeds up installation and produces a clean, professional finished appearance without extra hardware.
• Innovative carbon-steel cutting thread limits total carbon steel in the anchor - less carbon steel means less expansion in the base material, helping preserve the integrity of the surrounding concrete or masonry.
• Made from Type 316 stainless steel - provides superior corrosion resistance in salt water, chemical, and highly corrosive environments where lesser materials would fail prematurely.
• Single-use design - installing the anchor only once preserves full thread integrity and maintains rated load capacity, protecting the reliability of your installation.
• Installs with an impact wrench or by hand tool using a 3/8 in. wrench - compatible with common power and manual tools, so crews can work efficiently without specialized equipment.

Why This Product

• Built for the harshest conditions - Type 316 stainless steel is the optimal material choice when anchoring in salt water, chemical, or highly corrosive environments, offering a level of corrosion resistance that Type 304 and carbon-steel anchors simply cannot match in extreme applications.
• Dual-material engineering solves a real installation problem - the combination of a stainless steel body with heat-treated carbon-steel cutting threads lets the anchor cut cleanly through concrete while keeping carbon steel content - and unwanted expansion - to a minimum, resulting in a more precise and reliable set.
• Seismic and static load qualification removes guesswork - for contractors and specifiers working on projects with strict load requirements, having a single anchor qualified for both loading conditions simplifies product selection and supports compliance documentation.
• Straightforward installation with standard tools - no proprietary drill bits, no separate washers, and compatibility with both impact wrenches and hand tools means faster installs and fewer items to source, keeping projects on schedule.

Frequently Asked Questions

Can this screw anchor be removed and reinstalled in the same hole?

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.

What type of drill bit is required to install this anchor?

No special drill bit is required. This anchor is designed to install using standard-sized ANSI tolerance drill bits with a 1/4 in. diameter.

What makes Type 316 stainless steel the right choice for my application?

Type 316 is the optimal choice for applications in corrosive or extreme environments such as salt water, or when chemical or corrosive solutions are present, providing superior long-lasting corrosion resistance compared to other stainless steel grades.

Is this anchor rated for seismic applications?

Yes. The Titen HD screw anchor is qualified for both static and seismic loading conditions, making it suitable for use in seismically active regions and demanding structural applications.
