There is a reason for the original screws’ design. When socked in tightly (use your hand impact driver), the washer head provides a seal that prevents leakage around the screw. “tightly” in this case means the impact driver as already mentioned. It also explains whey they are always buggered up—because people try to get them out with inadequate tools.

Hey, correct screws are available. Some even not too badly beat up.
