Old hinge snapped a rivet. It could no longer hold the weight of the door.

I removed the two screws and pryed out the old hinge. I then put in the new hinge. The new one fit well. I went to screw it in with the supplied screws. The screws not only did not fit the hole tapped in the hinge (too big, different tread) but both screws were different from each other. They were different sizes and different types all together. I tried re-using the screws from the originol hinge but they also did not fit. I then got my own self tapping machine screws and finished the job. This job should not have been that hard. If they had supplied the correct screws, It would have taken all of five minutes.
