Pull test at Simpson Strong-tie seminar May 10, 2012. Riverside manufacturing plant.
1/2″ Titan threaded rod holder. 2500psi concrete.
This is a bolt that you just drill a hole and then screw into the concrete with an impact gun. It is designed to hold things like large electrical conduit tracks from concrete ceilings. You just set the bolt and then you screw a piece of threaded rod into the top of the bolt to suspend what you need to..
This bolt can easily suspend the full weight of my Dodge 1 ton dually.
