In rereading my post above, I apologize if I came across harsh, as I do not mean to do that. I hung around engineering and machine design for some time, so fasteners were just a tool to me.
Everyone has areas of expertise and it would not be reasonable to expect anyone not familiar with a process to understand it.
The web is full of complaints regarding designs made by those who just do not understand the process. Hopefully these comments will serve to educate. Go to any thread on Buckmarks and you will see condemnation of threaded joints by folks who just do not understand the principles.
Always armed, I would like to have the hours back we spent fighting galled stainless steel fasteners over the years
