Does anyone have the exact specification sizes for the Empeg faceplate standoff bolts? The four long hexagonal bolts which extend out from the display board PCB, into which the faceplate hex screws screw into.

I've stripped one and I want to order a bagful of them to keep on hand. I just need to know what the exact numbers are that I need to search for on the internet. I do not trust myself to be able to reverse engineer the exact specs by measuring the parts myself by hand.

This information might have been in the FAQ (I remember posting a picture of one of those snapped bolts to the FAQ once), but alas, 'tis down. I am sad that I do not have a backup file of any of the FAQ entries to confirm/deny if the specs are in there or not.
