I saw where he mentioned GE cabinets, and all the ones I've seen had 10-32 threaded holes or holes drilled to the size to thread as 10-32. In fact, the Mastr III's I helped install 2 years ago were set up for that, and we had some minor issues with the racks the customer wanted them in, since they were the 12-24 style microwave racks, and we didn't have any 12-24 screws...emergency trip to nearest hardware store... Now Motorola cabinets on the other hand mostly have 1/4" holes for the tinnerman nuts he was talking about...
