Purchased these to replace original plastic clips that were starting to become brittle and break from the sun. I did not use the supplied screws, instead I used stainless steel self tapping screws that I supplied. As to what others have mentioned about not fitting in existing holes from old clips. I prefer them to not fit in same holes. This way I know that these will be tight. Just put sealant in old holes before installing these. The base of these clips covered existing holes so really it wasn't an issue.
