These are good set screws, and YES they are stainless. Just because they stick to a magnet does NOT mean they are not. There are different grades of stainless. For instance 304 will not be magnetic. 18-8 however, which I believe these are, will stick to a magnet even though they're are nearly identicle in composition.
