I’m mounting a hammock chair to my ceiling using 2 eye-bolt plates rated for 160 lbs max load. The plates came with 4 screws meant for wooden joists, but after drilling a pilot hole, I realized the apartment has metal joists.
Since I couldn’t find any info on how to properly mount anything heavy on a metal joist online, I was wondering if anyone here knows what I should do to properly mount the chair? I read about using metal-sheet screws or toggle screws, but since the metal joists are hollow, this doesn’t seem appropriate for a hammock chair (meant for light swinging, as it will be indoors)
