wondering if anyone has used Well Nuts to fasten their downriggers to their gunwale. I have flush mounted rod holders that i use gimbal mounts for my downriggers and some of the mounting bolts are unreachable to hold the nut from slipping. I was wondering if i used a well nut there, if that would supply me enough strength. how strong are these. will these hold up to the abuse of a downrigger gimbal mount????
