Can T Get Set Screw Out Of Shower Handle

A shower handle set screw usually gets stuck because of mineral buildup, corrosion, or a stripped hex socket. The practical fix is to apply a mild dissolving treatment first, then retry removal with the correct Allen key before moving to destructive methods. One plumbing support guide recommends soaking the area with a 50 percent distilled white vinegar solution for about 30 minutes to loosen buildup around the screw.
