    Bach Strad finger buttons have a 6-36 thread, which is quite a bit smaller than 6mm. In addition to needing buttons with the correct threads, they need to have the correct underside offset to maintain proper valve alignment. I'd stick to buttons that are advertised to specifically fit Bach Strads.

    Bach thread sizes are American (6-36, major diameter 0.138"), which happens to be close to the metric 4.0 x 0.7 (major diameter 0.157") which is used by Yamaha. Close is not exact enough for my taste. Also, as Dale points out, the skirt height is critical to achieve proper valve alignment.

    So there is basically no way to get cheap buttons, right?

    I found a bach gold trim kit for 100 usd (used). So maybe I'd better buy this

    We also have a member here at TM that might be able to make you some custom finger buttons (I say might because I don't know if he's taking orders yet). He started a thread about it not too long ago...maybe check that out?
