Countersunk Screw

Thank You for your report.

Maybe the moisture and the salty air chould be cause. I also learned about anti size. Further i also will apply this.

500ft beach run - jogging or really touch and go?

Thanks and Greetings

I always tell folks not to over tighten these two screws or use a thread locker. Your anti-seize idea should be fine. You could also use for this small project nickel anti-seize. 

@HKK: my bet on height, not length ;-)
