Type 304 Stainless Steel Heavy-Duty Screw Anchor by Simpson Strong-Tie is a premium concrete and masonry screw anchor engineered for fast, efficient installation with long-lasting corrosion resistance. Combining the durability of Type 304 stainless steel with innovative heat-treated carbon-steel cutting threads, this anchor is the ideal cost-effective solution for wet, moist, or damp environments where reliable performance and clean installation are essential.

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
• The THDSS has an innovative carbon-steel thread that 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 for reliable corrosion resistance in wet, moist, or damp conditions
• 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 in the same hole?

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.

Does this anchor require a special drill bit for installation?

No special drill bit is required. The Simpson THD75700H4SS is designed to install using standard-sized ANSI tolerance drill bits with a 3/4 in. diameter drill bit.

What tool is needed to install this anchor?

This anchor installs with an impact wrench or by hand tool using a 1-1/8 in. wrench size, making installation straightforward without the need for specialized equipment.

What is the difference between Type 304 and Type 316 stainless steel for this anchor, and when should I choose Type 304?

Type 304 is a cost-effective solution for less extreme applications where the environment may be wet, moist, or damp. 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. Choose Type 304 when your application does not involve exposure to those more aggressive conditions.
