The HDU series of holdowns are
the latest in a long series of innovations from Simpson. These
holdowns combine the advantages of low deflection and high
capacity from the pre-deflected geometry.
The HHDQ series of holdowns
combine low deflection and high loads with ease of installation
by using Simpson's patented SDS screws. They may be installed
either flush or raised off the mudsill.
The STHD is an embedded strap tie
holdown with high load capacity and a staggered nail pattern to
help minimize splitting. The latest version of the STHD strap
tie holdowns incorporates many new features.
