So you dropped that bolt you really needed on your roommates’ bedroom’s once white now grey shag carpet while working on your bike using their tools without permission… and it vanished? Like your stash of N.O.S. Lunchables (now with extra Cadmium!) went missing from the chest freezer after Larry drank all the Zima?  Or did that fender set you just acquired only come with non-stainless hardware? Damn those Teutonic rain protectors.  Well we've got your back! As much as a bike shop via the internet can.  

Of course we also have nice aluminum stand off spacers, stainless washers, nylock nuts and probably some grease made out of boiled down Crystal Pepsi. 

All M5 bolts have a head diameter of 8.5mm. Head Height of 5mm. Use a 4mm allan key. 18-8 stainless steel. Bolts up to 25mm long are fully threaded. Bolts over 25mm have 22mm of thread.

All M6 bolts have a full thread to 30mm. Over 30mm, they have 24mm of thread. 10mm head diameter. Head depth 6mm. Drive size: 5mm wrench. 18.8 stainless steel.

Use beeswax to make sure these (or almost any other bolt) don't shake loose.
