A:Answer I had exact same problem with my Samsung 50 inch. I tried several hardware stores that carried metrics with no luck I had to use the longer screws and hacksaw them to the correct length. If I had to do it again I would try a motorcycle shop like that sells one of the Japanese brands (Honda, Suzuki, Yamaha, or Kawasaki). I'm sure they would have a metric to fit. Just make sure you bring in the screws that came with it so the can match the threads.
