Review on 🔓 Fastener 014973264895 Core Door Anchor - An Elusive Find Made Easy by David Epps

I've looked everywhere for this. Everyone has their own type of cavity for drywall. They are designed for hollow doors, panels and thin plywood. They are easy to use. Drill a 5/16 hole and gently push the base into the wood until the spikes dig into the wood. Once the screw is tightened, it expands relative to the wood. Be very careful when using a drill to turn a screw. I would recommend using a screwdriver to avoid damaging the screw.
