Metric Bolt Kit
I find it handy to have a variety of metric stainless bolts around when assembling bicycles. My kit is running a little light and some other friends wanted similar ones, so we put together a bulk order from McMaster Carr. I thought I’d document the kit that we put together while I had the part numbers handy.
This spreadsheet shows a nice kit which can be split among 4 friends and costs about $30 each at today’s pricing:

There are a few changes from my old kit above. I dropped the longer M5 bolts because I don’t use them very often. I added some M6 bolts in a length that I find useful for cantilever brakes and seatpost binders. I also added some button head M5 bolts in the sizes that I use for direct mounting fenders.
This is brilliant. I wanted to do the exact same thing, but I hadn”t come up with a proper list of hardware yet. This should be a good start.
This is a great list, and at some point I”ll have to break down and make an order. I”d like to get some more flange button head screws, I love those for direct-fender mounting, they make me feel better about not using a washer.
Jimmy — I over ordered slightly I think. If I have an extra kit I”ll drop you a line. I thought about over-ordering a lot (knowing that you and a few others would also be interested), but didn”t want to put too much on my CC.
I can”t read the why! Why Alex why?
No m4? No m8? I find those m4′’s useful for random fender/reflector mounting and m8′’s for, uh, maybe just the seatpost binders on the kelly frames I have. Hmm, maybe thats why I don”t ever go through them.
I just never use much M4 stuff, so I don”t mind paying hardware store prices.
My blog cut off the Why, but you can read it in the RSS feed. I don”t know why it does that.
