This is a very basic beginner question. I need to replace half a dozen
Blum hinges on the kitchen cabinet doors. These are recessed Blum
hinges. They are held in their pockets by two small screws. I am
afraid that when I replace the hinges they won't be held securely since
the screws will go into the existing holes. What can be done to make
sure the new screws hold the hinges securely even though they are
screwed into the old holes?

Thanks!
