If you want to install the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13182 on your 2016 Jeep Grand Cherokee, you will use M14 bolts that are grade 5 as well as compatible flat washers. That is the replacement for what is missing from your vehicle. If you want stronger bolts you can use grade 8 as some like to do but almost all hitch hardware is grade 5. The factory bolts use a 21mm socket. The length of the bolt is not mentioned so you will need to use your best judgment.

I've attached a video to assist as well as the installation instructions.
