No offense here, I am going to pull a frnash here, "unloosened" would be to tighten. You needed to "loosen" the screw. Kind of like the often misused term "unthaw", which would mean to freeze rather than "thaw". You have been officially Nashed.Got the board replaced, just needed to scrape out sand in the dock screw so it could be unloosened. Thanks.
X2Buy somewhere else you don’t want one board thicker than the others to trip over.
