Simpson Strong-Tie Titen HD 5/8 in. x 8 in. Type 304 Stainless Steel Heavy-Duty Screw Anchor is a premium heavy-duty screw anchor engineered by Simpson Strong-Tie for demanding concrete and masonry applications where long-lasting corrosion resistance and high-performance load transfer are required. Combining the proven undercutting ability of heat-treated carbon-steel cutting threads with the durability of Type 304 stainless steel, this screw anchor delivers fast, efficient installation and peace of mind in wet, moist, or damp environments.

Key Features

• Qualified for static and seismic loading conditions
• Thread design undercuts to efficiently transfer the load to the base material
• No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits
• Hex-washer head requires no separate washer and provides a clean installed appearance
• Innovative carbon-steel thread effectively cuts the concrete while significantly limiting the amount of carbon steel in the anchor; less carbon steel, less expansion
• Made from Type 304 stainless steel - a cost-effective solution for less extreme applications where the environment may be wet, moist, or damp
• Combines the corrosion resistance of Type 300 Series stainless steel with the undercutting ability of heat-treated carbon-steel cutting threads
• Caution: Use a Titen HD screw anchor one time only - installing the anchor multiple times may result in excessive thread wear and reduce load capacity

Frequently Asked Questions

Can the Titen HD screw anchor be removed and reinstalled?

No. The Titen HD screw anchor is designed for one-time installation only. Installing the anchor multiple times may result in excessive thread wear and reduce its load capacity, which could compromise the integrity of the connection.

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

No special drill bit is required. The THDB62800H4SS is designed to install using standard-sized ANSI tolerance drill bits, making it convenient and straightforward to use with commonly available tooling.

What tool is used to drive the Titen HD screw anchor?

The anchor can be installed with an impact wrench or by hand tool. A 15/16 in. wrench size is required, and the hex-washer head eliminates the need for a separate washer during installation.

Why is Type 304 stainless steel used instead of Type 316 for this anchor?

Type 304 stainless steel is a cost-effective solution for applications in environments that may be wet, moist, or damp but are not exposed to extreme corrosive conditions such as salt water or harsh chemical solutions. Type 316 would be the preferred choice for those more extreme environments.
