A stripped screw hole in wood means the original threads or surrounding fibres have failed; the right repair depends on hole diameter, substrate and the load the fastener must carry. This guide lists five reliable repairs, when to choose each one, exact step sequences, recommended adhesives and tools, plus special handling for plywood and particleboard.
Quick Decision Guide
Choose by three factors: the hole condition and diameter, the panel type, and the expected load. Use glued toothpicks for small, light-load holes; hardwood dowels or plugs for shear-loaded fittings such as hinges; two-part epoxy for crumbling cores or cosmetic rebuilds; and metal threaded inserts where hardware will be removed repeatedly. For a fast refresher on basic screw direction and torque control see the site primer on which way to tighten a screw fast.
Toothpicks and Glue: Fast, Cheap, Effective
Use this for small holes in solid wood that hold light hardware, for example trim screws or small cabinet knobs. The glued-fill technique rebuilds enough bearing surface for a single or occasional fastening but will not tolerate repeated removal or heavy shear.
- Remove the screw and clear loose fibres with an awl or pick.
- Coat plain wooden toothpicks or matchsticks with PVA wood glue and pack the hole tightly.
- Trim flush with a sharp knife after glue squeeze-out, allow full cure (about 24 hours for PVA), then drill a pilot hole slightly smaller than the screw core and reinstall the fastener.
For short-lived fixes or where cosmetics matter this method is fast and inexpensive; for hinge locations upgrade to a dowel or insert.
Dowel or Wooden Plug Repair: Strong and Durable
Reserve this method for oversized or damaged holes under shear load, such as door hinges, cabinet hinges or mounting plates. A correctly sized hardwood dowel recreates continuous grain contact and restores the best shear strength without introducing metal parts.
- Enlarge the existing hole to a clean cylinder with a drill bit that matches the dowel diameter.
- Cut a hardwood dowel slightly longer than the hole depth, coat with PVA or polyurethane glue, and tap it fully home.
- After full cure, trim flush, sand, then drill a pilot hole through the patch sized to the screw core and fasten.
When hinge screws have previously stripped, follow the door-frame repair sequence rather than repeating toothpick fixes; see the stepwise door-frame guidance at how to repair wooden door frame.
Epoxy and Two-Part Fillers: Rebuild Crumbling Cores
Choose epoxy for delaminated plywood, crushed particleboard, or cosmetic fills where you need a sandable, solid patch. Two-part systems permit shaping and produce a dense core that holds threads well when fully cured.
- Clear dust and debris and ensure the hole is dry.
- Mix the epoxy or putty exactly to the manufacturer ratio and press it into the hole; for extra capacity press a short hardwood dowel into the wet epoxy to form a core.
- Overfill slightly, allow full cure (12-24 hours depending on product), trim and sand flush, then drill a pilot hole and install the screw.
Use slow-cure epoxy when you need working time for shaping; use a higher-modulus, rock-hard epoxy for structural loads. For a compact, practical overview of epoxy and filler options see the engineer-focused summary at Engineer Fix: How to Fix a Stripped Screw Hole in Wood.
Threaded Inserts and Metal Fixings: Repeatable and Heavy-Duty
Install metal threaded inserts where hardware will be removed frequently or where consistent torque and long-term reliability are required. Inserts are appropriate for appliance mounts, removable cabinet hardware and some door-frame hardware.
- Drill the hole to the insert manufacturer’s specified diameter and depth.
- Install the insert per the manufacturer instructions; some screw in, others are pressed or hammered. Use locking adhesive where the insert documentation recommends it.
- Screw the machine screw or bolt into the metal thread; if the insert is recessed, trim and finish the face as needed.
Metal threads eliminate future stripping and provide repeatable removal torque. If you are unsure which insert type to choose, the site article on cabinet hardware installation describes typical fasteners and hardware loads at how to install cabinet hardware.
Special Cases: Particleboard, MDF and Plywood
Particleboard and MDF lack continuous grain and crumble under repeated torque; dowels often fail at the core. For particleboard prefer epoxy-filled repairs or chipboard anchors designed for that substrate. For plywood, treat the panel like solid wood if the core layers are intact; use dowels or epoxy where the core has delaminated.
- Particleboard: use anchors made for chipboard or install an insert; avoid toothpick repairs for hinge loads.
- Plywood: use hardwood plugs or epoxy-filled cores for edge or delaminated holes to restore bearing strength.
| Method | Best For | Typical Cure Time |
|---|---|---|
| Toothpicks + Wood Glue | Small holes in solid wood; light loads | 24 hours |
| Hardwood Dowel or Plug | Hinges, heavy loads, repeated use | 24 hours (glue); trim after cure |
| Two-Part Epoxy or Putty | Crumbled holes, particleboard, cosmetic fills | 12-24 hours depending on product |
Tools, Adhesives and Safety Essentials
Essential tools: a drill/driver with a selection of bits, hardwood dowels, toothpicks or matchsticks, mixing tray for epoxy, clamps, a flush-cut saw or sharp utility knife, and sandpaper. For adhesives, use PVA wood glue for general interior dowel and toothpick repairs, polyurethane glue where moisture resistance is needed, and two-part epoxy for structural fills.
Wear eye protection and a dust mask when drilling or sanding. Work in a ventilated space when using solvents or epoxy and follow all manufacturer safety instructions on glue and epoxy packaging. For guidance on screwing into repaired or nonstandard substrates consult the primer on can you screw into wood filler.
Fastener Selection and Pilot Hole Guidance
After any repair, drill a pilot hole sized to the screw’s core diameter. For softwoods use a pilot about 60 to 70 percent of the screw root diameter; for hardwoods use a pilot closer to the root diameter to avoid splitting. Replace damaged screws rather than forcing them back in, and increase screw diameter only when the patch material can accept the extra engagement.
Common Mistakes and How to Avoid Them
- Overtightening. Stop when hardware sits flat; overtightening crushes or compresses the patch and causes early failure.
- Rushing cure time. Load joints only after adhesives reach rated strength.
- Repeating weak repairs. If a patch fails repeatedly, move the fastener location slightly or use an insert designed for repeat removal.
- Using toothpicks in high-shear positions. Use dowels or metal inserts for hinges and door-frame hardware; see practical removal tips at need help removing a stripped screw.

Where to Buy Repair Supplies
For convenience, consider a ready-made wood screw hole repair kit that bundles dowels, plugs and basic fillers. Choose a kit that lists dowel diameters and a small selection of threaded inserts if you anticipate repeatable hardware removal.
Final Editorial Judgment
Match the repair to the load and substrate: toothpicks for short-term light loads, hardwood dowels for shear-critical hardware, epoxy for crumbled cores and particleboard, and metal inserts for repeat removals. When in doubt, move the fastener to fresh wood or use a metal insert rather than relying on repeated quick fixes; that decision prevents recurring maintenance and preserves the surrounding joinery.
