If it were mine, I would drill it out to the next larger size, which is most
likely going to be an SAE size.  I would paint the bolt head as a reminder
that I'm gonna need a 9/16ths (or whatever) wrench on "that one".  Maybe
even use a magic marker and write the wrench size somewhere nearby on the
mounting plate.

I can't imagine a helicoil being as strong as new threads in virgin steel,
though I don't think strength is as critical as the helicoils' tendency to
come out when you remove the bolts.  Either way should work fine.

|This is definitely an idea...

|
|But, maybe a larger bolt *is* a better option?
|
|Am I underestimating how hard it is to put a helicoil in?  Moving to a

|this the hardest part of the helicoil job?
|
|I am thinking that the helicoil should be as reliable as the original
