The ceiling hook pulled out after a season — the drywall dimpled, the fixture came down, and now you are looking at a wall repair you did not budget for. The thread did not bite deep enough. This No. 10 ceiling hook has a 2-1/16-inch thread that bites into wood or drywall and holds under normal load. The steel body resists bending if someone bumps the fixture or tugs on a hanging plant. No. 10 thread size covers the most common ceiling hook and hanging fixture range — the size that works for heavier pendant lights, ceiling fans with rated hangers, and decorator fixtures. Standard on the hardware inventory of finish carpenters and property managers across northeast Nebraska and northwest Iowa — the ceiling hook that stays put when the fixture does not.
