How do I fix a screw hole that has wallowed out?
| Hole | Drill to | Plug | Pilot for the screw |
|---|---|---|---|
| Small screw, hole 3-4 mm | 6 mm | 6 mm hardwood dowel | 2 mm |
| Hinge screw, hole 4-5 mm | 8 mm | 8 mm dowel or a glued plug | 3 mm |
| Structural screw, hole 6-8 mm | 10-12 mm | Face-grain plug, glued | 4 mm |
| Hole at a board edge | Cut back and glue in a block | Same species block | Fresh pilot |
Why dowels work: end grain in the dowel is not what takes the screw. The screw bites the long grain of the dowel wall, which is why the plug has to be a tight fit with glue, not a loose splinter.
The pilot matters more than the plug: a pilot 0.2 mm oversize in softwood strips again in a season. Test the pilot on an offcut of the same timber before drilling the repair.
