I am replacing the double demountable hinges on my cabinets. Most of them are a breeze, but two of the narrow cabinets don't have the cutouts; instead, they just removed the plate and screw from the hinge, kind of making it single-demountable. They then just used a wood screw to attach the hinge directly into the cabinet.
However, I can't figure out how to actually get the screw out of the cabinet-side plate of the hinge. Here's a new hinge looks like just sitting on the counter (even though it kind of looks like it's attached to it):
It looks to me like there's some kind of nut/lockring on it, but when I try pliers and a screwdriver to loosen it, it just strips the metal of the nut/lockring away. The lockring turns along with the screw, no matter how hard I grip the lockring.
Does anyone have an idea how to get this screw out?
Also, in case it helps, the hinge is Amerock BP8700-G10

It looks like a lockring is used to hold the screw in place. You'll have to hold the screw still and rotate the lockring, or vise versa.
Using a flat-head screw driver and mallet, is a common way to rotate lockrings. Though, you'll have to find a way to hold the screw steady, while you bang the lockring free.
It's possible that the lockring is made of some type of softer metal, so grabbing it with pliers could easily damage it. Using a screwdriver and mallet applies force only in a useful direction, whereas pliers apply non-useful forces required for gripping. These non-useful forces may damage the lockring.
