Clean my threads?

[brianplaugher]

My serotta repaint looks nice, but we have some paint in various threads which I would like to run a tap through to clean up. I have a set of metric taps, but can anyone remind me of the correct tap size for: bottle bosses, dropout adjusting screw holes, rear derailer, 6 mm seatpost clamp?
Thanks,
Brian Plaugher

Bike tools etc has a lot of taps and their intended purpose. I know the sizes but sometimes I get the pitches wrong.

Bottle Bosses: M5x0.8
Dropout Adjusting Screw Holes: M3x0.5
Rear Derailleur: M10x1
6MM Seatpost Clamp: You mean it uses a 6mm allen key? Please measure the O.D. of the threaded section first. If it measures 8mm, then it's an M8x1.
