Cosmos works bolt connectors

I have been working with a model that is bolted with a clearance hole in cover and a threaded hole in base. There is pressure applied to the pockets in the base. If I use the major dia of a 1/2-13 bolt I get a large stress around the edge of the threaded bolt hole. I tried a chamfer on the bolt hole and induced more stress. I then tried to use the minor dia on the base with the same 1/2" bolt. The stress was less. Is this the proper way to model threaded holes using the minor dia? If not what is the proper way to model for threaded hole connectors?
