Replace wheel hub bearing bolts

Hi!
I'm currently in the process of replacing my front hub bearing. Only managed to get one of the three 12p 13mm bolts out. The rest are made of 100% rust.
And I'm about to cut the bolt head off with my dremel.
Can I replace them with normal bolts (6p 13mm ) ?
What size are the threads ?

Thanks in advance !

I replaced them as you described, works just fine. Don't remember the size. Just go to your box that says "everything" and find the ones that fits.

I'll go to the hardware store and get some 10.9 (grade 8) bolts tomorrow then, thanks !

And I will never trust anyone on JF saying a job is "easy". Took probably 8 hours getting the old hub out. Think it's the first time anyone change hubs on my WG/WJ -99 (214500 km/ 133284 miles)

Having done that job on XJ's and WJ's many times I've found that it's much easier on a WJ than XJ's. Lots of PB and some leverage generally gets the job done. Don't forget to reassemble with anti-seize. You will be back there again. Note: Two required substances for every Jeep owner are PB and anti-seize! Get some.

It was pretty straight forward. Nothing is easy otherwise women would do it. Just takes mucho PB blaster and a lot of leverage. I did both fronts in a couple hours with a dinner break in between. That's after they've been on there thru 12 Chicago winters and 140,000 miles. Good Luck!!

Need leverage. A very large breaker bar that you can put your sockets on does the job with a lot of PB blaster.
