McMaster Carr sells M8 dowel pins. Depending on type, you can get internally threaded for $1.50, or standard ones for $10 for a pack of 5.

Or you can print an 8mm dowel pin for almost free :)

Not for an extruder idler bearing.

Really? Why not? I do that for all of my printers with Wade-style extruders. Works well. I do print them horizontally though, with a flat spot on the bottom so it sticks well to the bed.
