Bolt Size for rear brake reservior plug?

[NewfoundlandVenture]

Hi. I am wondering if anyone knows how I can find out a bolt size, thread size, etc. The part number is 90153-10015-00 and it is the fill plug from my rear brake reservoir... I took it out this evening, and dropped it when it came out of the hole... can't find the dang thing anywhere!

 

Thanks!

I can tell you its NOT an 8mm bolt. My plug is missing, bought a 8mm x 16mm at Home Depot, wasn't large enough to fit in. Was going to try a 10mm next time I stopped by there.

M10x1.25 mm Thread. That's the same than the Banjo Bolts are.

Don't forget the crush washer.
