I've managed to strip this middle screw here under the grab rail cover.
How can I remove this and where can I get the correct replacement screw? I've been going at it with an extractor bit set but have made very little progress. Not sure how the screw stripped in the first place. I'm assuming there must be some serious threadlocker on the screw.
If vice grips don't work, is there enough room for a Dremel to cut a groove across the head for a blade screwdriver ?
To best use an extractor, get a set of "left handed drill bits" which work like normal bits, but in the reverse direction. About 50% of the time they are used to drill an extractor hole in a bolt/ screw, their reverse bite will actually catch and turn out the bolt without even needing to use the extractor. Hope this happens, because the problem with an extractor is that if they snap off flush, their are just awful to get out.
Don't try removing any more fasteners until you first get the correct size hex wrench, Phillips or blade screwdriver that matches it.
