A video ad says, "Holds up to 150 lbs.!" Just "Twist! Push! Turn!" this wire hook into drywall, plaster, or paneling. We found a packet of 20 hooks for $14.99.
Staffers used hooks at home in various wall materials. In the lab, we hung progressively heavier weights on hooks pushed into drywall.
Hercules Hooks get the hook. Although they were easily pushed into drywall and wood paneling, they got hung up if they hit a stud and were very hard to force into plaster. A single hook is strong enough to hold 40 pounds or more, but holes in drywall tore at that weight. Brackets, picture hangers, and even nails hammered into a stud are better for heavier objects.
