How do I fix a stripped screw hole in wood or particleboard?

Evidence grade: B1 — Trade practice Effort: Easy · 30 min + glue cure · toothpicks or hardwood dowel, wood glue or epoxy, drill bits

Short answer: the hole holds because screw threads bite into surrounding wood fibers — once those fibers are torn away, you have to give the screw new material to bite: wood + glue for light-duty holes, a glued hardwood plug for heavy ones, epoxy fill for particleboard. Pick the method by substrate and load, not by what's closest [1][2].

Why the hole failed

Screws grip because their threads wedge into the wood fibers around them. A hole strips when those fibers are torn away — by over-tightening, by a screw driven without a pilot hole, or by repeated removal [1]. Toothpicks don't fix the hole; they fix the fibers — they restore material for the threads to bite.

Method 1: toothpicks + wood glue (solid wood, light duty)

1. Dip toothpicks (or wooden matches/golf tees) in wood glue and push them into the hole until it's packed — snap off the excess.
2. Let the glue cure fully (overnight is safest).
3. Drive the screw back in. For best results, drill a fresh pilot hole through the repaired material first [1].

Method 2: hardwood plug/dowel + pilot hole (solid wood, heavy duty)

1. Drill the stripped hole clean with a bit slightly larger than the damage, then glue in a hardwood dowel or plug with wood glue.
2. Wait a full 24 hours for the glue to cure — the dowel must be one with the surrounding wood before it carries load.
3. Drill a new pilot hole in the center of the plug and drive the screw [1].

Method 3: epoxy fill (particleboard / MDF)

Particleboard crumbles instead of holding fibers, so toothpick repairs are unreliable there.

1. Fill the hole with epoxy putty: knead it, push it into the hole with a screwdriver, and scrape off the excess before it hardens [2].
2. Let it cure fully — never drive a screw into uncured epoxy; the hole must be drilled after cure, not formed by the screw.
3. Drill the correct pilot hole through the cured epoxy, then drive the screw [2].

Also for particleboard: ordinary screws pull out of particleboard by design. Use 2.5–3-inch coarse-thread screws with washer-style heads, and always pre-drill — un-drilled particleboard splits and the repair dies with it [2].

⚠️ Stop rules

• The particleboard around the hole is crumbled, swollen, or blown out — no fill method restores the substrate's strength. Reinforce, relocate the fastener, or replace the panel.
• Load-bearing hardware (heavy door hinges, wall-mounted brackets) on particleboard — a repaired hole in particleboard never regains full holding power; through-bolt, back it with solid wood, or hire it out.
• Structural connections where failure means injury — the methods above are furniture-grade, not engineering-grade.
• PPE/ventilation: eye protection and dust control when drilling (especially MDF/particleboard dust — wear a dust mask); nitrile gloves and ventilation for epoxy per the product label.

Honest limits

• A glued toothpick repair is a light-duty fix — it restores fiber for the screw to bite, not the joint's original engineered strength.
• In particleboard, even the best epoxy fill can't recreate the board's factory density around the hole; treat repaired particleboard connections as gentler-duty than new.
• Matching the original screw type (coarse thread, right length) matters as much as the fill — a fine-thread screw in particleboard will strip again.

Fill-and-redrill is an epoxy-class job: a two-part structural 1:1 epoxy suits the fill method above on wood and particleboard — cure it fully, then drill the pilot hole.
