Repair a stripped screw hole in particle board
Use 2-part epoxy putty, not wood glue and toothpicks. Particle board is loose flakes; the putty cures into a plug you can drill and drive a screw into.
This task involves: Gap or poor fit, Load-bearing / shear
Best Glue for This Repair
Fills the voids between crumbs and cures into a solid plug you can drill and drive into — the only repair that does not depend on sound wood grain.

Why 2-part epoxy putty Works Here
- The staple material of flat-pack furniture. Because it is pressed from large wood chips rather than continuous grain, it has very low internal tensile strength and is extremely prone to screw tear-out and water swelling. Liquid PVA glue is quickly absorbed into the porous edge voids, so rebuilding blown-out holes requires 2-part epoxy putty or expanding polyurethane rather than thin PVA.
- Hand-kneadable epoxy putty or gap-filling liquid epoxy anchors screws and rebuilds blown-out hinge holes in crumbly board.
How to do it
Repair a stripped screw hole in particle board: Step by Step
Epoxy on skin and eyes
- Back the screw out and pick the loose flakes from the hole until you reach board that still holds together — or the factory face, if the core is gone.
- Knead 2-part epoxy putty until the color is even and pack it into the hole, slightly proud of the face.
- Leave the plug still until the putty has fully cured. Do not drive a screw into soft putty.
- Pare or sand the proud putty flush, then drill a pilot hole smaller than the screw.
- Drive the screw until it is snug. Stop before you crush the board around the plug — that face is still particle board.
Conditions
When to Use Expanding polyurethane glue Instead
A hinge or rail that still wiggles after the plug has cured means the board around the hole has crumbled too far. Cut the damage out and glue in a hardwood dowel, or move the hardware to sound board. PVA will not save a blown cam-lock or hinge cup.
Alternatives
Other Adhesives That Work
Foams into a wide, empty blowout when you have no putty. The foam is weaker than a packed epoxy plug and harder to drill cleanly.
Better when: Gap or poor fit

Wood glue (PVA) with toothpicks
The toothpick trick needs sound grain for the screw to bite. Particle board is loose flakes; PVA soaks in and the flakes pull out when you torque the screw.
Questions
Common Questions About This Repair
- Why not use the toothpick and wood-glue trick on particle board?
- That trick needs sound grain for the screw to bite. Particle board is loose flakes. PVA soaks into the voids and the flakes pull out when you torque the screw. Pack the hole with epoxy putty instead.
- Should I glue in a hardwood dowel instead of putty?
- Use a dowel when the hole is so wide the putty would be a fat plug with almost no board around it — a blown hinge cup or cam-lock. For a normal screw hole, putty is enough and does not need a saw.
- Will epoxy putty hold a kitchen cabinet hinge?
- Yes, if some sound board remains around the cup. If the face crumbled in a ring, cut the damage out and glue in a dowel, or move the hinge to a new hole. A putty plug in powder will spin with the screw.
- Can I drip super glue into the stripped hole?
- No. Super glue cures brittle and cannot fill a crumbly cavity. The screw shatters the plug the first time you tighten it.
