 I betcha the FIRST officials in the know come in here from time to time and either gasp and think of how to make next year's clue harder or fall off their chair laughing. - Sparks333 [more] |

We standardize to the extent possible on 1/4-20 and 10-24, shcs or fhcs. The only exceptions are motors that require specific threads, or situations that demand a larger fastener (specifically a larger size, rather than higher strength)
The reason? Cost. In high strength fasteners, coarse threads are slightly cheaper. I doubt you could find a well designed FIRST bot where you need the strength of more than a quality 1/4-20 fastener. And the course threads give us the option of tapping into wood, polycarb, aluminum or steel without much issue. Two box wrenches and two allen keys will take the bot completely apart and put it back together. Last edited by Dan.Tyler : 10-02-2014 at 13:32.
