More on boat cleats
Nuts are metal not plastic. They had a flat washer and ring washer. Have to assume they were never tourqued at the factory. No way getting up there using the cushion opening. To tight and to long. Called a dealer. Told me to remove the front upper cushion and cut holes in the fiberglass. Also. Cushions are screwed in from behind. No way to get there. Pried them off, cut two holes and used lock tight. Hope that works. Cleats are factory installed. They would have to be!!!!
Thanks for trying.
