Does anybody know a good source for metric bolts with an Allen head? I recently was involved in re-assembling a bike, and I'm not happy with one detail. I've accumulated some bolts over the years, but I didn't have enough to do this project. As a result, I've got many different sizes, I'm using washers as spacers in some locations because the bolt was too long, and I've got some that I bought at a local auto parts store which require the use of a wrench (which I normally don't carry with me) to tighten.
Any ideas? The guys at the auto parts store looked at me like I had two heads when I tried to explain what I was looking for.
