Practical trick
Use a pilot hole to reduce splitting
Drill a small guide hole before driving a screw near an edge or into harder timber.
Works well for
- Small timber fixings
- Near-edge screws
- Cleaner screw starts
Do not use for
- Unknown wall cavities
- Oversized holes
- Skipping eye protection when drilling
What this trick does
Drill a small guide hole before driving a screw near an edge or into harder timber. It is best treated as a light-duty, inspectable DIY trick, not a permanent or critical repair.
How to do it
- Mark the position clearly and check for hidden cables or pipes before drilling.
- Choose a fixing that matches the material and the likely load.
- Drill a pilot or plug hole where the method requires it.
- Drive the screw or fixing straight and stop before the head strips or sinks too far.
- Test gently and reassess if the wall, timber or fitting feels weak.
Where it works well
Use it where the job is small, visible and easy to check afterwards. If failure would matter, use a proper product, fixing or repair instead.
Common mistakes
- Treating a temporary trick as a permanent repair.
- Applying too much force and damaging the workpiece.
- Forgetting to inspect the result after a few minutes of use.
Safety note
Check for hidden cables and pipes before drilling. Wall fixings depend on wall type and load. Do not invent load ratings. Heavy items need appropriate fixings, judgement and eye protection when drilling.
