the bolt was a little rusted and the head gave like warm butter (cheap a$$ bolts). If I drill through it, won't there be the possibility that I will not be able to run another bolt through that thread? :-/
the dealer service techs drilled out a bolt that I'd broken the head off... if you try drilling it, you'll have to use a smaller sized bit than the threaded hole... I've never done it before so can't tell you from 1st hand exp. They probably tapped it out with a punch or something after drilling a hole through it.
I stripped a stainless hex screw i put in my coffin reservior and mercilessly dremeled at it for some time trying to get it to fit with a square bit (harder than i thought). i dremeled away some paint in the messy process. a friend happened to have some left-handed screw extractors so i abandoned the torture and the screw came out with no effort!!! if you can't get at the inside end with some needle-noses i highly recommend the extractors to be easy on your surrounding components and nerves!
