Good to read that.
But what fancy thread is this anyway?
Internal 60 degree Vee thread 0.400" full threads long, 2 threads max lead out.
Pitch 0.03125"
Max diameter 0.146" +/- 0.001"
Root diameter 0.104" or 0.105" +/- 0.0003, 32 microinch or better
Pitch diameters 0.1235", 0.1245". 0.1256" and 0.1270" no tolerance specified.
Material 360 leaded brass
Seems to be the UN #7-32. http://www.practicalmachinist.com/vb/general/7-32-screw-size-does-even-exist-251655/
What is the customer screwing in for that root diameter? Does he want to fly to Jupiter with it? You can form tap and tell the guy that the male thread has to have crest flats and radius. Sorry for my excess energy. Foolish thing
