Hi I need help removing screws from the side of the cabinet hinge found inside the cabinet carcass. Turning the screws does nothing to loosen them out, they just spin around. The screws seem to be inserted into some kind of green plastic spacer and then into a metal threaded dowel insert coated with plastic which anchors the screw. Even when I hold the metal/plastic threaded dowel piece at the end with locking pliers, the screw still won't budge out. I've already completely stripped one of the screw heads trying everything. We want to reuse this piece instead of buying a whole new hinge.
It would also be nice to know what the green spacer thing is actually called too since I can't seem to find the part on the internet. I'm afraid to cut it off since I don't know how to replace it.
