Rick, I think he means screw diameter and thread count. Not the size of the torx bit. But I could be wrong. I've tried to buy them at home improvement stores before and have come really close, but still haven't found ones that will fit precisely. Anyone who knows the answer will win the ultimate Oakley Trivia Challenge!!! (hey that sounds like a thread that will be started very soon by unnamed parties....you know who you are.)
Luiz, if you do find a source for these hard to find screws, please let the rest of us know. Thanks.
