The Draw-Tite Max-Frame Trailer Hitch Receiver # 76031 referenced in your question is confirmed to fit your 2014 Infiniti QX60. I went through the installation steps and found that the 8.8, M12 x 1.25 x 35mm bolts you mentioned are the correct size for your vehicle.

The issue you are experiencing with fitting the bolts into the existing holes in your vehicle's frame is actually not too uncommon. Since the frame of the vehicle is constantly exposed to dirt, moisture, and salt, this gunk can find its way into these open bolt holes and harden over time. This can lead to the provided hardware with a trailer hitch seeming like it is too big for the factory frame bolt holes.

What you can do is use a wire brush # 814092 and some spray lubricant like WD-40 to clean out the holes. You will want to spray the lubricant into the hole and let it sit for a few minutes. Then simply scrub the bolt hole with the wire brush, rigorously running the brush in and out of the bolt hole. You can repeat these steps until you are able to twist the bolt in a few threads.

I have attached an article that goes into a bit more depth on this very process, along with a video demonstration that you can use for reference.
