Contact cement or impact adhesives (Evo-Stik type) aren't ideal for glueing on thumbrests or 'curing' loose screws - they are used for glueing on key corks and tenon corks but apart from that, they don't have much use on woodwinds.

It's best for sticking things to other things with a relatively large surface area that aren't structural or will be put under a lot of stress - the surface area of a thumbplate base is far too small to be secured in place with Evo-Stik and sooner or later it will come adrift.

If a screw hole in a wooden instrument body has stripped, it's best filling in with something far more durable which is either superglue or epoxy, then drilling out and finally fitting the screw. Even if a wood screw has been bonded in epoxy or superglue, it can still be unscrewed.

In a severe case where the screw won't hold at all, the hole can be driled out larger and bushed (by superglueing in a grenadilla plug turned down to fit tightly), then made flush with the surrounding joint surface and polished, then drilled out so a wood screw (or pillar) can be screwed in again and hold the thumbrest on.

It's pretty easy to do and saves a lot of fart-arsing around with the wrong kinds of glue which will fail.
