Fill holes with toothpicks and glue
If a screw turns but doesn’t tighten, the screw hole is stripped. Here’s a quick remedy: Remove the screw and hardware. Dip toothpicks in glue, jam as many as you can into the hole and break them off. Either flat or round toothpicks will work. Immediately wipe away glue drips with a damp cloth. You don’t have to wait for the glue to dry or drill new screw holes; just go ahead and reinstall the hardware by driving screws right into the toothpicks.
Repair a cabinet hinge screw hole with a plug
Cabinets made from particleboard work great in utility and laundry rooms, and they’re fairly inexpensive. But particleboard has a major weakness—it doesn’t hold screw threads very well. So if you swing the door open too fast, the force can rip the hinge screw right out of the cabinet wall. Don’t worry; the fix is easy and cheap. Here’s how to patch things up. You’ll need a bottle of wood glue, a 1/2-in. drill bit and a package of 1/2-in.-diameter hardwood plugs (sold at home centers).
Start by removing the hinge screws on the cabinet and flipping the hinge out of your way. If the accident pulled out a large chunk of the particleboard, glue it back into place and let the glue set up before proceeding with the rest of the repair. Drill out the stripped screw hole to accept the plug. Next, fill the hole with wood glue and install the plug. After the glue dries, drill a pilot hole and install the new screw—you’re all set.
