well simple answer is they can be, but not the way they are sold. The have a steel screw inside them and a spring. so if you were to find a suitable stainless or plastic replacment for the spring and screw then they would be fine. I was looking at another brand that is 100% plastic construction, I will see if I can find out what they were called again.
