I have counterbored m12s into 20mm plate. The 8mm left between the head and the extrusion is plenty enough.
I think that looks like the best solution. There 20mm so 8.4mm thickness left according to solidworks. Now the question is, do I attempt to drill them out and re-bore myself or send them back and get them re-done professionally? I'm worried about the drill bit wandering off from centre.

Well that's up to you! My build has been decidedly diy so I'd have to do it myself! I would have thought the bit would find its centre in the existing hole...Quote:

They look very good! I assume you used a drill press? (mine is an el cheapo one and has a bit of play in the head). Did you use any kind of guide for the bit?
No, no guide and my press is only a table top Axminster thing so nothing pro! Attachment 17513
Minor detail not worth stressing over. Domed head look fine without being counter bored so don't bother just drill them out to 12mm.Quote:

Fair point but I have to say counterboring is strangely pleasurable!!
Bling Bling.!!!!Quote:

Also - if you counterbore you could cap the holes with diamonds to complete the look!!
