I'd use wash away stablizer. Nothing at all left under the threads

washawy is THE way to go...... spritz al ittle water and BAM it's gone....

Don't u just hate it when u lose a screw??????

been there done that and what a mess.

shop returned machine with new screw, they couldnt find it either. told me to put a note on the machine for when i have it serviced and the service tech will look for it. at least I got it back with the ok to use it.
