With leftover nuts and bolts, how much is too much?
Dear Car Talk: I have a question that’s been gnawing at me. For many years, I ran a gold mine in remote Alaska. During that time, I had to do a lot of mechanical work on all kinds of equipment and vehicles.

For instance, let’s say you’re rebuilding your engine, and you put it all back together, and you find a single
