Find a machinist / model engineer locally and they can make you exactly what you need. Look for ‘model engineering society’. There may even be a register somewhere. I no longer have access to a lathe otherwise I could have knocked something up.

Hilti appears to have a UK branch. They have a variety of steel washers (at least in Canada). Check their site and hopefully you can find what you need.

I have a lathe (it's 90 yes old and a hobbyists even at the time) but I can turn a stack of washers down myself I think

Can you not bore out the m6 center with a properly sized drill bit?

Time to get turning then!

I was in a similar position recently I needed a 40mm washer with an m4 hole. It was impossible to find I had to use a smaller one.

Figured reliably doing that without it biting given the low grip area would be very difficult
