Posh washers

If you have access to a lathe, or know someone who does, why not drill and turn a mild or stainless bar to OD and ID required, chamfer to suit, part off as many as you need. Far cheaper than buying them and may be less time to make them than searching for them.

Don't need any plating paint or oiling for corrosion resistance if you make them in stainless.

That's what I do, although I have the luxury of a repetition lathe which simplifies production once it is set up:

As 0BA is 6mm OD you will have more luck finding M6 ones and may even be able to get away with M5 for the 2BA.

Accu do both

Trouble with making washers is that you make as much swarf as washers unless you can find a zero thickness parting tool

Have you tried asking your local nut & bolt supplier for 'T&C' washers (Turned & Chamfered)?

I’ve not needed to make any for a while but in the past I’ve made extra thick “machine washers” for clamping setups. Standard washers always seem a bit thin for this or is it just me?

They probbly stamp them out of strip plate nowadays

Yes hardware store washers will bend etc as they are made of malleable Chinese cheesium. If you buy Grade 8 washers from a fastener supplier they will last a lifetime for clamping etc.

Given the small size if you don't have access to a lathe.

Get some grade 8 washers. place them on a bolt with a nut to clamp them then chuck them in an electric drill and then carefully file the chamfer.
polished up with fine wet and dry paper both in the drill and on the face they should look fine.

On this side of the ditch suppliers refer to these as Williams Washers. I keep several sizes under the lathe. The ones I purchase from Fastenal tend to be on the hard side which provides for an even torque without scoring or damaging the material at hand.
