You can get screws at a sewing machine repair shop. The guy who does my tune ups checks all the little things like that to see if there's anything that's broken or there's any problems with the screws or anything else and he changes it out for me. Great job explaining how to clean the machine wonderful tutorial. The vacuum wasn't loud very quiet. Hopefully you are having the Happiest New Years!! Namesta ✌️🕉️🐞
