Have a tuba at school and the screw was always coming loose, and todays the day it went missing. No sign of it anywhere. In particular the screw that attaches the leadpipe to the tuba. Any one know where to get one? Thanks in advance

You can order them from Conn Selmer. Is it the screw that connects the receiver to the bell or the one farther down the leadpipe?

EDIT:

I read the original post WAY to fast, and offered a completely WRONG selection.

I HAVE bought some "just the thing" 2341 detachable mouthpipe screws from McMaster/Carr, but don't remember (offhand - at least not sitting at my laptop) their thread size nor exact length.

I’m guilty of doing it but using steel screws in brass should normally considered a temporary measure, the risk is that someone will over-tighten the screw and strip the thread (expensive to repair such permanent damage) in the other (softer) brass part. I’m a believer in light grade loctite - small screws and things moved by fingers need the lightest grade … don’t ask how I know.

As best I can guess it looks like there’s a screw halfway along he lead pipe and one next to the mouthpiece receiver.

Some interesting prices here, I guess that there are high handling costs to cover, glad I was sitting down: https://parts.conn-selmer.com/products/ ... btuba/2341
