Once I get these screws out, Do I need to replace them? I don't have these kinds of screws on my Infiniti. I think they are just here to annoy people who try to work on their cars. Another question, If I drill a hole in the center of this screw, wont I just end up with a stuck screw with no place to put a screwdriver into.. how will it just fall out? And wont I mess up the threads that this screw tightens into?
