Fixing striped stem end so shower knob can grip again?

Author: learningdiy (CA)

I've just successfully repaired a leaky hot water shower by replacing the washer on end of stem. I've confirmed this fixes the leak, but now unfortunately the Sayco handle is slipping and not turning the water on/off again. I tried out the handle on the other step and it grips fine, so it looks like the issue is the grooves on the end of the stem itself.

Is there any way to get some additional mileage out of the stripped end of the stem? I tried plumber's tape, but it wasn't enough to allow the handle to grip. Are there other plumber's tricks I could try?

Thanks in advance!

Author: hj (AZ) I knew a plumber who had that problem in his own house. He used vise grip pliers until he got ready to sell the house, then he replaced the stem.
