What I was not sure about was the cut outs in thread for the bolt to cut through the paint (like the bolts for the seats or for the horns) - did these bolts have it?
Otherwise, yes, I think they were quite generic M6 hex head bolts. But there are people here who can tell more/better.
I also do not know if they should be their natural color or they should be body paint color if they were painted with the hood, hinges and washers.
