I purchased a used Tow Hitch for a 2008 Frontier. It doesn't have the mounting hardware. Has anyone ever purchase the hardware? Are the bolts full threaded? Will I find them at Home Depot? Please help if you can.
Your rear bumper's steel sub structure is mounted to the frame with three bolts on each side that thread into welded nuts horizontally. These are the same size and thread pitch.
If you bring these to a fastener shop, someone there will easily be able to match it. Home depot or lowes is less likely, but still possible. No matter what, insist that you get grade 10.9 bolts. These are strong enough for the demands of automotive applications
