Magic bolt (Nuts will go to different direction when rotating)(double threaded bolt)

The magic bolt is a double-threaded bolt. It can be used as a normal M20 bolt that has two rotate directions, clockwise direction, and counter-clockwise direction. Another magic bolt can be used as a special bolt that has M20, pitch 2 mm, and 1 mm format bolt.

I add 0.2 mm and 0.3 mm clearance data together. You can choose one of them for your model.
