Oil drain plug gasket size

[Nessmuk]

I have a BX1500 and the local dealer has oil filters, but always seem to be out of the copper crush washers. I have looked and can’t find the thread size on the bolt. Anyone know the size? I am guessing all BX tractors use the same plug.

Lots of options…don’t even have to leave the house if you don’t want to….and lots left over for other projects:

Just ordered 150 metric copper washers in 15 different sizes. That should last me for a while. Thanks for the suggestion.
