Technics Sp-10 platter screws

Anyone know a source for a set of SP-10 platter screws?

What diameter is the bushing? I need the screws (although the table sounds fine without them,) but don't particularly want to pay the £49 the chap in England is charging.
A little "googling" taught me the original platter screws are "pan head shoulder screws." There seem to be several sources in England, or one could have them custom made in China if you needed several thousand or so. If someone with the original screws would be so kind to measure them with calipers, perhaps we could find a good match here:
