1350 uses bolts and nyloc nuts everywhere. It makes prototyping easy since we can easily build, test, and rebuild any part (easy until you find you built an integral structural or functional component directly over the bolt head you need to get to which can't be moved since EVERYTHING is bolted onto it, but thats OK, it builds dexterity). The real issue comes when everyone is fighting to use one drill bit or wrench that is the only one of its size and happens to be the correct one for EVERY bolt on the robot.
We also like zip-ties, but not so much for the chassis.
