There are a lot of little screws on clarinets, and I guess from time to time one may work itself loose and need to be screwed back in again. I have no problem with that. But, theres one particular screw that for no apparent reason is unscrewe every time I look at it, even if I only screwed it back in a few minutes ago. It's the one by the RH C# key, and if I don't notice it gets as far as to be nearly scraping the key. Its in an awkward place to get at without scratching the C# key too, so it really is tiresome to keep mucking around with it. Any ideas?
Thanks

Put a small dab of clear nail varnish on the screw head. This won't damage the clari, don't worry about that.

Mine used to do that all of the time as well. As Barry has said, I put some nail varnish on it and it seems to have sorted it, but I used sparkly nail polish; I didn't have any clear stuff!

Thanks! I will get hold of some, and try to keep it off the wood as well...
