I have had my rod holder screw/knobs come loose from the tapped bases. I did a little research on using thread locker on the stainless screws that thread into the aluminum bases. It doesn’t seem to be recommended. Not even medium strength. I have always checked them for tightness before leaving home and apron arrival at the launch I was missing one or they backed out to the point of being loose! Now this doesn’t happened often but my rod holders are expensive! The last thing I want to find at the launch is I’m missing a holder. Does anybody have a suggestion? someone said silicone might work on the threads. I would appreciate any ideas.
