Stress risers aside, I've been told the shoulder bolts might be a little bit
stronger. I know bolts tend to break at the minor diameter of the thread, so
I don't know why a shoulder would add strength, but my machinist buddy says
they do if the shoulders nearly bottom. Sounds goofy to me, but he swears
it's true.
