Query: Too small

I had a house with a pool 25 years ago, with an Intermatic timer. I found the trippers very hard to adjust through the year, since the screw heads are so small and the screws need to be fairly tight. Now I am in another house with a pool, and the same model timer, and the same trippers - they have not changed in all that time. You need to use pliers to adjust the trip settings, and before long the screw heads are worn, which makes the pliers slip. I'm amazed that there seem to be no trippers available with larger (wider) screw heads.
