What's the correct designation for the bolts sized to fit into water bottle and rack braze ons?

Thanks,

Gee, Nashbar seems to want 2 bucks a piece for those little bolts. ;-)

I was looking for the metric designation. Would these be the same as M5?

Yep...

From Sheldon Brown's website (http://www.sheldonbrown.com/gloss_ta-o.html):

"Metric bolts are sized by the diameter and the distance between adjacent threads, for example 6 x 1 refers to a bolt 6mm in diameter with threads 1mm apart. (This is the size used for brake mounting bolts and brake shoe hardware.) Similarly, 5 x .8 means a bolt 5mm in diameter, with threads .8mm apart. (This size is used for fender and bottle-cage fittings, shift lever bosses, and most cable anchor bolts.)"

So I think that means you want an M5-.8 x 15mm or x 20mm depending on the application.
