I bought some of these for work. They are prefect for testing electronics with potentiometers. Many testing specs call for potentiometers to be set to different degrees of rotation, I drilled a small hole in the center for these to slide over the post. They are thin plastic but inexpensive, they are prefect for what I need them to do.
