Default fine vs coarse
Forgot to also include a benefit of coarse thread fasteners, the greater thread depth results in better resistance to wear from repeated removals and installation - probably a major reason why they are common in cheaper consumer products. I've seen the aftermath of a helicopter main rotor blade separate from the hub on a balance stand because the fine thread bolts were not changed at a reasonable interval. Fine thread is more precision.....
