Bindings Coming…

Last season I had a problem with my bindings comming loose from the board over the course of the day. I’d ride for a while, and eventually the binding bolts would be loose and my bindings would be able to swivel/wiggle back and forth but still be attatched to the board. I’ve tried tightening them down as much as I could (without stripping the threadings) and using blue loctite but with no success
