In my opinion one of the better ways to fasten things is the bolt then weld technique. Bolt the thing together, get it to work correctly then weld it up and remove the bolts. This works very well for "add-ons" to the frame that are not an entire mechanism. Things like axle blocks and wheel supports. It also saves weight. Our rookie year we used the kit chassis for a while, but we welded it together, saved almost 8 pounds!

If it hasn't been made clear by now, each type of fastener has an ideal job and most robots will use multiple types. We have metal screws, nuts & bolts, threaded pieces and welds this year. In the past we have also used wood screws and rivets.
