I got so tired of miss placing bolts, or using them for something else, that I bought an assortment of washers and grade 8 bolts in various lengths, and have a whole drawer in my tool box dedicated just for bolts, nuts and washers. It makes life easy, no more searching for cans or zip lock baggies(which work great for disassembly and reassembly), I just open the drawer remove whats needed. Then when it's time to put them away, back into the drawer they go. I also have a Ace Hardware 2 blocks from my house, in time of need!
