Anything under 3mm will not create a countersink, tried on multiple machines and user accounts. is this a bug? or is this just following a standard if so which?

We are adding you to an improvement for pairing hole feature with Onshape standard content. Right now the countersink and hole feature assumes a standard countersunk socket head screw, and the sizes don't exist in the standard for these below M3. I'm assuming you want a countersink for something other than that fastener type. There are many different types of screws that require countersunk holes and they all require different sized countersinks based on their head geometry - even if they have the same thread sizing. Our hole feature needs to improve to let you pick specific fastener types to create a countersink for. Right now we only size the countersink for countersunk socket head screws and it's way too limiting as you are finding out (M2 and M2.5 is not a size for these fasteners). You are on the improvement that will address the shortcoming for you. We intend to let you create countersunk holes for any fastener that is in the Onshape standard content library. I believe the exact standard we currently use is this: https://www.iso.org/standard/34454.html#:~:text=Abstract,classes 8.8, 10.9 and 12.9.
For today, you can just type in the values you want for the angle and opening diameter size of the countersink - so you are not blocked in really creating any hole you need for any case, but certainly we want to automate this more for different fastener needs so that you don't need to be looking things up in more obscure tables for fasteners.
Understood.
