I am not sure about using screws. The shutter lol fasteners worked for me since they blended in well with the shutters and I have never seen caps
Most likely the original wholes drilled to large

Watch this video. I’m a 60+ grandma and I did mine with no problem. https://youtu.be/QGT7l5ZmTgw
We ordered new shutters and I didn’t know they came with plastic screws and metal. We have a brick home and we used the metal screws. I returned these plastic screws to the store.
apparently none come with the shutters... use screws as I did... much cheaper
