The Draw-Tite Class III # 76031 hitch installs using six M12 x 1.25 x 35mm CL 8.8 bolts, 1/2 inch flat washers and lock washers.

If your Pathfinder has been used in the rust belt where chemicals are used on road surfaces in the winter, there's likely some road grime and corrosion in the nuts that are welded up into the frame that accept the hitch mounting bolts. Before attempting to install the bolts, It's a good idea to spray each hole thoroughly with a spray lubricant like WD-40 and give the nuts a good scrubbing with a wire brush like a battery terminal cleaner such as part # DW00254. If there's lots of corrosion, you might need to do this a couple of times.
