The flat disc is to protect the plastic spring guide from the adjustment screw.On the adjuster, you either stripped the screw or the mounting hole in the breech plug. I suggest drilling and tapping for a whole new screw because it's not something you want to "slip"..unless you are able to determine which of the two (if not both) are stripped...
