Screw mounts and fiberglass

I want to put some mounts on the ceiling to hang gear hammocks. Any suggestions for the type of screws? When I did the shelves in the hanging locker I used wood screws because they had the biggest thread bite (there a real name for that?) of the stuff I could find but I snapped at least one and generally felt they were not strong enough...

Thanks,
J

Expoxy a wood strip or block and screw into that. You maybe happier.

The reason you snapped it off was because you either did not pre-drill it or you pre-drilled with too small a bit.

Use self tapping or sheet metal screws. Wood screws have tapered threads and shaft. If you drill a hole big enough for the shaft in FRP, the hole is too big for the threads. Woodscrews are for WOOD with it's unique elastic abilities.

Self tapping screws should be more than adequate for mounting gear hammocks. Some boats even had the hull to deck joints fastened with sheet metal screws. I also understand Hunter used the same fasteners to attach fittings. Definitely not reccomended but an idea of how strong, though not for long, sheet metal screws are.

You could stick BigHeads (no commercial interest- just a keen enthusiast) to the glass of your deckhead: then use your choice of fitting onto them- SS eyebolts, or eyenuts, or just bolts'n'washers... The BigHeads can be glassed on, or epoxied in place. You CAN even make your own!
