Rounded AC compressor bolt

I am attempting to change the water pump and timing belt currently. I’ve been following the TRQ video to a T and when I got to the first AC compressor bolt it started to round itself. I don’t want to necessarily extract it, screw the head up and then be out one bolt. None of the shops where I live will be open tomorrow so I’ll have to get one Monday. Anyone happen to know the dimensions of the bolt?

 

Not off hand, can you use a grip socket or an RBT socket to remove it?

 

@Tundra2 tried but that space is a little tight and I can’t really hit the grip socket on there

 

Is the radiator out of the truck? You can remove that for more clearance

 

yea it’s out. Last resort is to weld a wrench onto it lol

 

Do you have any impact guns? Sometimes you can beat a standard socket onto a metric bolt to get it our
