There are a few schools of thought on when to use a coarse vs fine thread. Most machines are engineered the way they are around those thoughts. Being in the bolt & nut business for over 37 years I've seen people make some bad choices in fastener selection even with best advise. TOH has listed some good points regarding thread selection for your project. Metric fasteners are another ball game. German vs Japanese fasteners can give you up to 4 different theads for one diameter, different wrench sizes for industrial vs automotive and it's a true learning lesson figuring out the bolt hardness. I would hate to be a true mechanic these days with the added expense of tooling up to do your job. As a fastener distributor I'm use to metric conversions, as an "American" I refuse to convert anything to metric. At the end of the day would be believe fine thread fasteners are a nickle and a dime more than coarse thread. Just my two cents.
