Yes, tighten them all the way down. Torque them to the recommended torque for that size bolt (6mm). Honda manuals give a torque requirement for a lot of things, some manuals don't have a torque requirement for certain bolts, but there is a section showing general torque values based on the bolt size. I don't remember what the values are off hand but I think for 6mm, it's around 8ft/lb.
