As evidence that I am becoming WAY too compulsive.....
I just made some scale 6-40 nuts in the proportions of "heavy hex" nuts. The thickness and across flats dimensions were easy to figure out from Machinery's Handbook specs. The detail I couldn't find in several reference books or on the web though, was any spec for the bevel that breaks the corners on the top of the nut. I used 30 degrees, but I think that may be a little shallow, and I think that to be strictly correct it should perhaps be a large radius.
Have any of you guys obsessed about this detail? What did you do about it?
