You can rivet them. Mine are. Aluminum rivets won't corrode the mast. There really isn't a good reason not to go up to a #12 machine screw.
Of course there are epoxy materials such as JB weld in liquid or in a stick. I'm not sure that they would produce a lasting repair. What about backing nuts? Ever heard of riv-nuts? They go in like rivets but are threaded for a machine screw fastener. Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Wed, May 2, 2018, 9:12 PM Matthew L.
