frayed, i used these, not sure what you call them. *i got them at west marine. *i mounted them on a small piece of wood and "5200"ed them to the underside of the lip on the deck. you need to use something that will let you move it around until you get all in and tight and then will set up
pics aren't too good. its a threaded flat washer with teeth to sink into wood. look in the fastner section of west marine they also work great on the rod boxes in the gunnells
