bolt size for trailer hitch holes
Posted: Tue Oct 25, 2005 9:14 pm
Does anyone know what size bolts (diameter and thread) fit the pre-drilled holes meant for mounting a trailer hitch? Before the salt and snow start spraying up in there this winter I want to spray some WD40 in them, put a washer around a bolt and screw a couple in to protect those threads from salt and sand.
