If you look online you can buy metric fasterners by the assortment that work out to be a pretty good deal. I think my last box of 6,8 10, 12 mm in assorted length ran $50.00 or so and will save lots of trips to the store mid project. I think I got them from Rocky Mt ATV/Cycle but am not 100% on that.  Otherwise I think the parts page you access on Bike Bandit and others will give you the fasterners size after the part number. If not most of the fasterns you are looking at will be 6 mm x 1mm pitch. 10, 20, 25, 30, 35 etc mm long. Most ACE hardware stores also have good selections. Most frame to accessory fasterners will be 8.8 strength (that will be marked on the bolt head usually). Some critical engine parts will be 10.9 strength. Max

Yeah, ACE even carries chrome in many stores but it's a lot more expensive.  I went with stainless myself.

For the best prices & selection, check yellow pages under Nuts & Bolts. The places that sell nothing but nuts & bolts are the places I go & I get low prices. The only drawback is not being able to go thru bins & look for a certain size that I will recognize, but can't explain. Then, Ace hardware would look like a great deal. I will be using them in the future, too, since the nut & bolt place isnt open on weekends. But, if I was gonna place an order of any size, I would go with the specialty shop.
