Product Description
The Simpson THD75400H6SS Titen HD 3/4 in. x 4 in. Type 316 Stainless Steel Heavy-Duty Screw Anchor by Simpson Strong-Tie is engineered for demanding concrete and masonry anchoring applications in corrosive and extreme environments. Combining the superior corrosion resistance of Type 316 stainless steel with innovative heat-treated carbon-steel cutting threads, this heavy-duty screw anchor delivers fast, efficient installation alongside long-lasting performance - making it the ultimate choice for salt water exposure, chemical environments, or any application where corrosion resistance is critical.
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 316 stainless steel for superior corrosion resistance - the optimal choice for applications in corrosive or extreme environments such as salt water, or when chemical or corrosive solutions are present
- Size: 3/4 in. x 4 in.
- 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
