Are there metal screws that aren\’t magnetic?

I am making a small maglev (Magnetic Levitation) model train and need screws that I can use to screw the wooden track pieces together without interfering with the magnetic field. I’m using incredible powerful rare earth magnets for the train car and the track. I can use plastic screws if necessary, but I’m worried about the heads coming off and the plastic not being a very long term solution. Any ideas would be great. Thanks!
