Don't worry about it! I appreciated the input. I bought some M2.5 screws and they fit. Very strange. I guess there are minor iterations in the vacuum or something. Agreed its very frustrating that they are so difficult to source. The screw should come in the box with the replacement brush. Cheers and thanks again.
