Re: Got Weight?
Last year I ordered aluminum nuts and bolts for my team. Bolts, nuts and washers are made of steel which is much heavier than aluminum(about 5x as much). Most bolts and nuts also don't take even close to the load necessary to break or bend them. We didn't build our robot with them, but I took an inventory of the major bolt sizes we used and brought boxes of aluminum replacements to the competitions. Whenever we needed to change a part we optimized it with aluminum parts.

I've also heard of team using plastic hardware which is 1/3 the weight of aluminum and I guess 1/15th the weight of steel.
