There is good news and bad news about the screwhole patterns of semi-concealed cabinet hinges. The good news is that most semi-concealed cabinet hinges made today use a center-to-center screwhole spacing of 2-1/8″ on the “Face Frame Wing” of the hinge.
The bad news is that there is no standard screwhole pattern for the “Door Wing” of the hinge. Every manufacturer uses a different screwhole pattern (and a close match is of no help because the screws will go in at an angle). You will find that even hinges made by the same manufacturer will have different screwhole patterns on the door wing. In the recent past there were dozens of companies manufacturing Semi-Concealed hinges. Today there are only a very few companies that make this kind of hinge since most of the market today in cabinet hinges is the European style hinge. For this reason you are going to find that trying to find a match for your old screwhole pattern is an almost impossible task. Since we are talking about the screwhole pattern on the back of the door, this is really not that big of a deal. You can simply fill the old holes and redrill new ones. In many cases you do not even have to fill the old holes because the hinge plate will cover up the old screwholes. The good news here is that since all of this is on the back of the door it is not in a visible place.
