Wow! I didn't think this message got posted. When I hit submit I recived an error message. After a few tries I gave up. Good discussion.
In regards to MintJulep's sidetrack about tolerancing: Just because the standard tolerance is good enough for most of the dimensions on the drawing doesn't...
My company has a long history of designing all in fractional or architectural dimensions, except the rare case where you need a tolerance to the thousandth. We deal with mostly castings (sand castings) and fabricated (welded) items. Being a younger engineer I was only exposed to working in...

I would like to suggest changing from a slotted type locknut to a "nylok" type because of extensive galling we have seen in some applications. Both the nut and threads were stainless steel. The application involves the chamber where the fastener is located being flooded with hot, dirty...
