Geez. Well, I guess it is good for standardizing but a 5/8" bolt is pretty darn big for an FRC bot. It depends on the application, but when you say "most of the bolts we use" it leads me to believe they are found in many applications, and are way overkill for lots of things. Getting some different bolts I think is a good idea.
This year, we tried to do as much of the hardware as possible in 10-24 and it worked out very well.
If there is a metric tapped hole in a part on the robot, there's nothing we can do about that. But other than that, we do English, and this past year, standardized English (10-24).
English is simply much easier when all your machine tools go by thousandths of an inch.
Also, metric hardware is EXPENSIVE here in the states and harder to find. For price, a bag of 10 metric washers (like M6 I think) might be like $1.80 when a bag of 25 1/4" washers (just the same for FRC purposes) is like $1.99. And if you get into nice black oxide allen head screws/bolts (like shcs or button head) then the price REALLY goes up. Also, at least at my LHS, the metric screws come in wierd quantities, like 3 to a package.
