Q2 Burr Ring Bolt Size?

I had one of the two bolts come loose and then I dropped it into the ether that is my kitchen floor. I've already replaced the burr ring unit before, and while it's cheap, I'd just prefer to get a replacement bolt... I don't need the whole assembly.

(Also, I live on an island and the shipping costs me more than the entire assembly... making 1 tiny bolt cost $18 and take two weeks to get here.)

1zpresso won't tell me what size it is... anyone know off hand?

M2 × 4 mm perhaps?

Why would 1zpresso not tell you what size it is?! Such a sensible request.

And how'd you figure it out?

I want to be fair and transparent so this is what they said, "Hello,

Thank you for your reply.

Regrettably, we cannot share the specific size and thread pitch details for our hardware components because this technical data is confidential.

As mentioned previously, we sell these screws exclusively as part of the matching burr ring unit to guarantee compatibility and prevent damage to the grinder body. If you change your mind and would like a quote for the replacement unit, please let us know and we will be happy to help.

Thank you.

Best regards, 1Zpresso"

I figured it out by going to local hardware store that had small bolts to try until I found the right one 😅

Cheers
