All hangers in this series have double shear nailing - an innovation that distributes the load through two points on each joist nail for greater strength. This allows for fewer nails, faster installation, and the use of all common nails for the same connection.

Simpson Strong-Tie HDU2-SDS2.5 Holdowns are pre-deflected during the manufacturing process, virtually eliminating deflection under load due to material stretch. They come with (6) 2-1/2" Simpson Strong-Tie® Strong-Drive® SDS screws which install easily and provide reduced fastener slip. Using SDS screws results in a greater net section, when compared to bolts, as no material is removed.
Simpson Strong-Tie offers a wide variety of bolted holdowns offering lowdeflection performance for a range of load requirements. All of these holdowns have been tested in accordance with ICC-ES's AC 155 acceptance criteria and are approved for use in vertical and horizontal applications.
The HD3B is a light-duty holdown designed for use in shearwalls and braced-wall panels, as well as other lateral applications.
