The holes are made for 3.5mm self tapping screw.
These items are used to get a good connection to the chassis of the vehicle. The chassis of the vehicle is mostly made of steel which is an electrical conductor.
But be aware:
Not every steel part of the vehicle is good enough for an earth point. Often some parts are only bolted to the 'mainframe' of the vehicle, so the current have to 'creep' over the thread of the bolts which in turn causes loss of voltage (=power).
Better is to find a part which is welded to the 'mainframe' where the battery is connected. This guaranties to have the whole iron available as conductor which then have a high cross section which in turn have a very low electrical resistance and very low voltage drop.
It is obvious that the earth point have to be made on a blank metal (rust protection with Zink spray).
