Yamaha rotor screw needed

Hello,

I have a Yamaha YBB-641 BBb tuba that is missing the screw that attaches the linkage to the rotor inserting directly into the main rotor shaft itself. I have large photos of this location on a web page at: http://www.angus1.com/tuba/part.htm a link should be below.

My local music store, which is not a Yamaha dealer but has the parts books, ordered this screw in for me but the part Yamaha provided will not fit as it has both a thicker shaft and different thread pitch. I have photos of what Yamaha sent and what I needed at the page address above and hopefully below as well.

Would anyone out there have a spare one of these screws or perhaps could one of the repair people in our group be able to tell me how to get hold of a correct screw. It is starting to get me a bit mental to not be able to make it through a full piece without having the linkage fly off the rotor. Might Yamaha have changed the size of these over the years?

Thank you for any leads or help
Paul Sidey
