Hello, I have an installation tool (which basically consists of a standard long bolt and nut) and a 100 lbs mass object would drop onto it (as if it were a hook) from about 1 - 2 inches. There are many forces to consider and I am looking into that. Since this installation tool will be reusable, I prefer not to have the threads deform too much over time. So I would like to know if there is a way to quantify the deformation on the threads as I drop the object onto it. It seems over my head. Thanks in advance for the help. See the attached image to get a better visual.
