Description

Simpson Strong-Tie® Pre-Deflected Holdown, Series: HDU, 3-1/4 in Depth, 3 in Width, 10-15/16 in Height, 14 ga Steel, Galvanized

HDU holdowns are pre-deflected during the manufacturing process, virtually eliminating deflection under load due to material stretch. They use Strong-Drive® SDS Heavy-Duty Connector screws which install easily, reduce fastener slip and provide a greater net section when compared to bolts. The DTT tension ties are designed for lighter-duty holdown applications on single 2x posts. The DTT1Z is installed with nails or Strong-Drive® SD Connector screws and the DTT2Z installs easily with Strong-Drive® SDS Heavy-Duty Connector screws (included). The DTT1Z holdowns have been tested for use in designed shearwalls and prescriptive braced wall panels as well as prescriptive wood-deck applications.
