The proper bolt has an extra-large 19-mm head so that it can be
operated with the same tool as the lug nuts/bolts.  Some PO lost the
one on mine and it presently has a 16-mm head which is a nuisance.

Suggest PB Blaster which is an excellent penetrant despite the
snake-oil appearance of the can, and will squirt in a fine stream
exactly where you want it.

Suggest measuring the bolt head - clearly either it has rusted
undersize or it's simply a different size.  If it's rusted perhaps a
good sharp pair of Vise-Grips will be a good bet?

For future consideration, a bit of antiseize on the bolt and more
frequent exercise when you rotate tires, check pressure etc. would
probably help.
