Replacing front diff plugs with bolts

I keep reading about all the problems people have stripping the 10mm hex plugs Toyota uses on the 2nd gen front diffs. Why didn't they just use bolts like on the transfer case and rear diff? And has anyone replaced their hex plugs with bolts? If so, what size are they?

Also some people say use anti-seize on the threads when reinstalling the plugs. Others say no. What's the consensus?

 

bump?

 

I have changed mine out five times now using a hex socket, and have not had any issues whatsoever. As long as your using a quality hex socket you should be fine, I dont see how you could strip out this hex bolt. Putting in a metric bolt would be a bit of an overkill IMO but to each their own, good luck with this it you do replace them, and get bolts that have a magnet on the base to collect shavings.
