I liked the idea of new screws. I have tapped out the threads with a tap to make sure you have good threads. Also take an air gun or some compressed air source and blow into the hole to remove any debris that may be in the bottom of the hole allowing the screws not to tighten.
Just for kicks I would also move both bindings forward one set of holes and make some runs. If you binding come loose in these new holes you will know it's the screws.
- Did you just get these or been using them for a while?
- Are the screws the original screws if you bought them new?
- If you got them used you sure they are the correct screws for those bindings?
The Screws for my Bent Metal, Flows and 51/50 are all different from each other
