I mostly used plastic washers. Regarding the terminals, I think it's a really bad design to use *any* type of bolt/nut inside a battery. The big cell I took apart had solid copper & aluminium blocks under the terminal, these finned out into many thin layers which became the active electrodes. No screws were in there at all.
