Location: On the X that marks the mucky spot | It all depends on how thick the aluminum is. I'd feel better with a nut/bolt combo with a dot of loctite (or equivilant). If you do use the tapping screws, just make sure you drill a pilot hole 1/2 the size of what you would for fiberglass. I'd also recommend that you use some marine grade silicon both on the screw threads and on the underside of the rail mounting area. That 1-2 punch should hold them fine. I know that's how I installed mine and they seem very strong. I can shake the boat on the trailer with that setup. |
