@Oregonerd the problem with increasing the scale of a bolt is though you are indeed increasing diametric clearance it messes with your thread pitch or axial position of each thread, becoming a compounding problem the farther you go.
There isn’t a change for threads in material when talking TPI and standard fasteners. Size and pitch is size and pitch regardless of material. There can be a change in connector type based on component compatibility or sealing properties, such as pipe threads. Pipe threads have a specific thread pitch like any other fastener depending on size but are on a taper. 3/4” per foot or 1°47” (same thing) which affectively causes the sealing affect as you tighten.
