Update: I switched from using a regular screwdriver to a JIS driver on a Pentax lens mount
I was fixing a sticky aperture on a Pentax ME Super last week and kept stripping the tiny screws. I was using my usual Phillips set. After three tries, I ordered a JIS #1 driver for $12. The difference was huge, it fit perfectly and didn't slip at all. Has anyone else found specific drivers that saved a repair?
