Thanks KENAT,
I attempted to look at ASME Y14.6 but our .pdf file is only accessible to the person/computer that downloaded it. As soon as I track down that "person" I'll look it up.
I had a previous customer that required tapped holes be called out with the decimal major diameter(.086)instead of the screw number (2). I haven't found an ASME specification that supports this. Does anyone know if there is such a specification?
