Simpson Strong-Tie HDU8-SDS2.5 HDU 16-5/8 in. Galvanized Predeflected Holdown with Strong-Drive® SDS Screws

Simpson Strong-Tie connectors make projects easier to build while making them stronger and safer, engineered and tested to perform and manufactured to the highest quality standards. HDU holdowns are pre-deflected during the manufacturing process, virtually eliminating deflection under load due to material stretch. They use Simpson Strong-Tie Strong-Drive® SDS Heavy-Duty Connector screws (included), which install easily, reduce fastener slip and provide a greater net section when compared to bolts.

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
