Thank you all for your quick response's, they are immensely appreciated.
I had a gut feeling these were the answer's...

Technically, the spec you quoted is for uncoated boards. You can thus
interpret it as you wish.
However, like everybody else said, a non-conductive washer is in order
here...

It is relavent when my PM is asking. While I know its not best
practice, I need to find what the correct answer is.

IMHO
It is irrelevant whether you violated any guideline or not. Do not ever
mount any conductive entity over a trace which then relies solely on the
SM for electrical protection.

Subject: [TN] Mechanical Hardware Clearance...
I have a board with a 15VDC trace on the surface layer that runs under a
flat washer.
The trace is covered by SM, which provides 500vdc isolation per .001 mil
of SM coating.
2221 states that any electrical conduction trace per sec 6.3 lists a
minimum clearance of .00512 to any other conductive surface (.ie
mechanical hardware)
Do I violate the spec.
Any help would be greatly appreciated.
