(OP)
Which grade of stainless steel which would not rust to Swimming pool water. A brand new set of stainless steel screws fastening the face plate to a skimmer (above ground pool) are rusting after a couple of months of pool operation. The pool water is chlorinated with tablets and occasionally softened.

To be safe find hardware in Monel or Al Bronze.

You might also want to look for screws with a more open head, such as square drive. They would drain better and be less prone to corrosion.
Though moving away from stainless is the best long term plan.

EdStainless is right, the carbon steel contamination from the screw driver is the culprit. Try the pickling bit too. Use silicon fill under the head to close any gap between the head and the plate. If feasible, cover the screw heads with silicon. Make sure to use 316 screws, not 304 or 400 series.
