I've just replaced the cloth & rubber fender on my Dyer Dinghy using a kit that came from Dyer. The screw they sent were Everdur. I had never heard of Everdur and did a google search. It came up mostly with articles from the 1930s. Maybe Dyer has decades old barrels of these screws that they're trying to get rid of? The screws seemed perfectly fine and I've already used them but was just wondering if you know anything about them. Educate me.
