I'm not trying to install a bumper I need to know what thread this 10 mm is. 1.0? 1.25?

There were 10 mm bolts in the holes but the thread was wrong and they only went in about 3/4 of a turn

Which hole? You could probably buy a small selection at your local hardware store for a few dollars. Try them out and you'll know.
