Looks really nice!
This might be obvious, but the way I did each mounting hole was to first drill the small hole for the bolt's shaft, then a large counterbore drill bit slightly bigger than the bolts head diameter and its socket OD. That way the mat lays flat yet you can get the socket on them to install easily. If you are using screws, you just need the screw head diameter OD for the larger drill bit. Masking tape around the bit is a good depth gauge on the counterbore drill bit.
