if you make, say, a 1:60 scale model. do you think you're going to take a 1" thk bolt and make it 16 thou dia on a scale model? what would even be the thread depth of the thread? a scale model doesn't have to be built like in real life. that's why they had engineers make the plans for actually building it. you know literally nothing about that industry and i can tell. i bet you've never even looked at elevation plans.
