We have ball end allen keys, t deal with, and a set of allen keys for 3/8" socket wrenches. If you have a universal joint for the socket wrench, you can actually fit the allen wrench into tight areas. The 2nd disadvantage of rivets is that they will just grab one wall of the box tubing.

If you bonded a few threaded inserts into your box tubing, and use a few 1/4-20's, you actually reduced your assembly/disassembly time. Our elevator assembly this year is a perfect example of quick assembly. To disassemble it, you must get rid of 7 threaded fasteners.

Both bolts and rivets can stand up to high tensions, compression and large loads if both material and size are part of the joint analysis. Since our robotic this year is half made of wood, we didn't use a great deal of rivets. We utilize a couple of wood screws to hold aluminum parts to wood, and some machine screws and nuts to hold other aluminum parts to wood.

We generally don't utilize locknuts on anything that may require to be dismantled for repair work or maintenance, due to the fact that it can take so long to get the screw out and back in.
