The HDU is designed for use in shearwalls and braced-wall panels, as well as other lateral applications in wood construction. The HDU uses Strong-Drive ® SDS Heavy-Duty Connector screws which install easily, reduce fastener slip and provide a greater net section than bolts.

Simpson Strong-Tie HDU Holdowns are pre-deflected to virtually eliminate deflection under load due to material stretch. The Strong-Tie HDU11-SDS2.5 pre-deflected holdown is installed with Simpson Strong-Drive SDS heavy duty connector screws which are included with the holdown.

The S/HDU series of holdowns combines performance with ease of installation. The predeflected geometry virtually eliminates material stretch, resulting in low deflection under load. Installation using self-drilling tapping screws into the studs reduces installation time and saves labor cost.
