A metric bolt labeled M6 1.0 x 50mm is a coarse thread bolt.
It's a 6mm bolt, with a 1.00 pitch, and 50mm long. You can find them at any hardware store in the loose bins.

use your fingernail. if it fits snugly onto the groove its coarse, if it sits on the ridges its fine.
hope this helps as this is the method i use..
